Welcome, adventurer!

We're so happy to have you on the team. This page is your home base for everything you need to know before we gather live on Zoom as a group — who's guiding, where we're going, what you're responsible for between now and October, and answers to the questions past teams have asked most.

The mission: one day, about 22 miles, roughly 10,400 feet of elevation change, and $10,000 raised as a team to create scholarships that get more women and girls outside. This hike is exclusively for women 50 and older — and we can't wait for you to adventure as a team!

Bookmark this page, then take 10 minutes to work through the Your To-Dos section below. Everything else can wait for our first team call.

Meeting location: Grand Canyon Village, South Rim, AZ. We drop from the rim toward the Colorado River and climb back out, starting and finishing on the same side.

Treat these numbers as our working plan, not a promise. Distance and elevation will move with trail conditions, with whether the river section reopens in time for us to reach the Colorado, and with what the group decides together on the day.

Closest airports: Phoenix, AZ (~3 hrs 40 min to the South Rim) or Las Vegas, NV (~4 hrs 30 min). Most of the team drives or carpools — more in Logistics.

Meet Your Guides

Sunny Stroeer

Professional endurance athlete, guide, and founder of the Summit Scholarship Foundation and AWExpeditions; co-owner of Kanab-based Dreamland Safari Tours. Sunny has completed the Grand Canyon Rim-to-Rim more times than she can count — including about half a dozen Rim-to-Rim-to-Rims in a day and two speed records. When she's not guiding, she's working to make the outdoors more inclusive through scholarships, mentorship, and trailblazing events like this one.

Angie Lake

Trailblazer Community Manager at The Cairn Project — the nonprofit initiative you're supporting through this adventure. Angie has hiked Rim-to-Rim-to-Rim and floated 300+ miles of the Grand Canyon on a 21-day rafting trip, finding awe in every canyon corner. She's a storytelling mentor who's excited to help you share your adventure with the world.

Your guides carry the safety net: GPS satellite communication, a group medical kit, and emergency shelter — plus extensive backcountry experience and deep familiarity with the Grand Canyon.

In Their Words

You'll be the third Cairn Project team to cross the Big Ditch. Here's what women from our first two Grand Canyon teams told us afterward:

"Even though I was tired and nervous, I felt strong and empowered. I sincerely believe that the beauty of the Grand Canyon and the badass women I hiked with carried me through the hike and made all the difference."

— Cyndee Llanos

"I never felt rushed or shamed for my pace and I know that was a part of my success and enjoyment."

— Aubrey Van Parys

"Women and girls deserve, not just to know, but to never have to question the fact that we are capable and deserving of all types of outdoor adventure."

— Erin Rush

The Route: Rim to River to Rim

Our plans changed, and here's why. September's flooding tore up the North Kaibab Trail and took out bridges, so the classic crossing isn't possible this fall. We're keeping the date and the effort and moving the whole adventure to the South Rim: down toward the Colorado River and back out the same side. It's a comparable day in distance, climbing and difficulty, in a place that could use the visitors right now.

We start and finish in Grand Canyon Village, dropping roughly 5,400 feet to the river and climbing about 5,000 feet back out over the course of about 22 miles.

  1. South Kaibab Trailhead — An early start, headlamps on. The steepest descent of the day comes first, so we go conservatively to protect knees and set the pace for a long day. Note there is no water anywhere on South Kaibab.
  2. At The Tipoff, turn onto the Tonto Trail — The flattest stretch of the day, and the one where past teams have felt suddenly fast after all that descending.
  3. At Havasupai Gardens, turn off the Tonto and drop to the Colorado River — The Gardens sit at the end of the Tonto and are our water stop. From there it's an out-and-back down to the river: the bottom of the Big Ditch, and our turnaround. Soak your feet, dunk your hat and shirt, and eat properly before we start up.
  4. Back up through Havasupai Gardens and on up the Bright Angel Trail — You'll pass the Gardens a second time on the way out, then climb the switchbacks to Bright Angel Trailhead. The steepest uphill comes at the end of the day; this is what we train for. Sunset is around 6 pm in October, so plan on finishing by headlamp.
Topographic map of the South Rim route: South Kaibab Trail down to The Tipoff, the Tonto Trail west to the Bright Angel Trail, down to the Colorado River, then back up Bright Angel to the rim. Elevation profile showing 11.9 miles of descending followed by 7.8 miles of climbing.
Rim to river and back, all on the South Rim side. Down the South Kaibab Trail to The Tipoff, west along the Tonto Trail, then onto the Bright Angel Trail to reach the Colorado River. From there we climb back up Bright Angel past Havasupai Gardens to the Bright Angel Trailhead. The profile shows the shape of the day: a long descent, then the climb out. Open the live map to zoom in, follow the trails, and click the track for your own elevation profile.

If conditions don't cooperate

The park expects the trail below the Tonto Plateau to reopen well before the 10th, but nothing is guaranteed. Two fallbacks, both of which give you the same rim-to-river day:

Water: the biggest change to your packing

The flooding destroyed the water pipeline. The spigots are off, and the park is trucking water in for the people who live and work at the rim. We carry in everything we need.

Plan for a minimum of 3 liters of capacity (up from 2 on our earlier plan). If you know you drink a lot, or if the forecast turns warm, carry capacity for 4. We expect 2 to 3 liters to be what you actually drink, but we want the extra capacity available rather than wished for.

There is no water from the South Kaibab Trailhead all the way across the Tonto until we reach Havasupai Gardens, so everything you drink before then is what you started with.

At Havasupai Gardens we'll treat water with AquaTabs, which take about 30 minutes and leave a mild taste. If you'd rather not wait or don't like the taste, bring your own personal filter — it's optional, not required. We'll confirm conditions in the final days before the hike.

Weather: two climates in one day

Rule of thumb: the rim feels like Flagstaff, the bottom feels like Phoenix. In October, expect lows in the 30s°F at the rim (it will be cold and dark at the start!) and highs around 80°F+ in the inner canyon. Sun protection is mandatory; layers are your friend.

Come ready for all weather. October should be the sweet spot, but the canyon does what it wants. Our March team hit triple digits at the bottom on a date that should have been mild, and then got cold on the climb out as conditions flipped in the same day. Pack the layers you might not end up using.

Heat also drives our start time. If the forecast runs hot, we'll start earlier to stay out of the worst sun, so keep your Friday evening loose and don't plan on a late arrival.

Your To-Dos

These are your responsibilities as a team member. Your progress saves on this device, so check things off as you go. The lodging items matter now — the water situation has scrambled where everyone is sleeping.

Do these ASAP

Between now and October

How the Weekend Will Flow

Exact times and meeting spots will be confirmed in your final arrival-instructions email about three days before the hike. Based on our past trips, here's the shape of it:

Training

Hiking across the Grand Canyon in a single day is HARD, and first-timers frequently underestimate it. What makes the canyon unique is the order of operations: a massive downhill first (hello, jello quads), then a climb of roughly 5,000 feet back out at the end of the day when all you want is a cold beverage, a shower, and bed.

The good news: this is a hiking challenge, not a running one, and steady training gets you there. Our 12-week plan is below. Counted back from October 10, week 1 is the week of July 20, 2026 — and it's completely okay if you're starting a couple of weeks in. Jump in at whatever volume feels honest and build from where you are.

The strength circuit is fully customizable — home, gym, weights, machines, or bodyweight only. If circuits are new to you, search "no equipment lower body workout" for easy-to-follow options. Prioritize downhill training (stairs, descents) and time on your feet over speed.

Gear List

You don't need fancy gear to cross the Grand Canyon — you need a carefully curated set of clothing, nutrition, and safety items. Conditions run the gamut from below freezing to hot, so plan to have every item below; once we can see the near-term forecast, some items (like the rain shell) may get cut. All in, your pack should weigh no more than about 10 lbs.

👕 Attire

  • Long-sleeve hooded sun shirt
  • Lightweight insulated (puffy) jacket
  • Lightweight rain shell or poncho
  • Lightweight trekking pants or tights
  • Brimmed hat
  • Light gloves
  • Beanie
  • Underwear
  • Lightweight hiking socks

🎒 Gear

  • Your preferred trail shoes — trail runners or lightweight hiking boots (broken in!)
  • Running pack or small day pack (<20 liters)
  • Hiking poles — not optional. Train with them so they're second nature by October, especially on descents
  • Headlamp with spare batteries (we start and may finish in the dark)
  • 3–4 liters of water capacity — the pipeline is down, so we carry everything in
  • Water purification (personal filter or Aquatabs)
  • Small personal med kit: blister care, ibuprofen, anti-chafe
  • Sunglasses & sunscreen
  • ID & credit card
  • Phone or camera!

🍫 Nutrition

  • 2,000–3,000 calories (2–3 lbs) of your preferred snacks: bars, gels, nuts, dried fruit, etc.
  • Electrolyte tablets
  • Pro tip from past teams: pack foods that will still sound appetizing when you're tired, hot, or cold — variety wins.

🧭 Guides carry

  • GPS satellite communication
  • Group medical kit
  • Emergency shelter
Headlamp tip: keep your spare batteries in a separate bag so the headlamp can't switch itself on inside your pack during the day.

Logistics

This fundraising adventure covers the guiding; travel, lodging, food, and park entry are on you. Three questions to answer:

1. How will you get to the South Rim?

By car. Fly into Phoenix or Las Vegas and drive, or carpool with a teammate. Carpooling matters more than usual this time, because our campsite allows only two vehicles. Sort rides in the WhatsApp group.

2. Where will you sleep, both Friday and Saturday night?

We start and finish on the South Rim, so you need a bed for Friday October 9 and Saturday October 10. The pipeline damage narrows this considerably:

Teammates are sorting rooms, campsites and rides in the WhatsApp group — post there rather than booking blind. And stash easy food wherever you land, because restaurants may well be closed when we finish.

3. Do you need a ride back?

No. This is an out-and-back from the South Rim, so we finish where we started and your car is waiting. Nothing to book.

Book your beds now. With Grand Canyon Village likely offline, everyone in the region is competing for the same Tusayan rooms. This is the most time-sensitive thing on your list.

Fundraising: Why We Hike

This is a fundraising adventure produced by The Cairn Project, an initiative of the Alliance for Gender Equity in Outdoor Adventure. The funds you raise create scholarships for women and girls to access transformative outdoor opportunities — a first night under the stars, a summit reached, a backpacking trip that builds confidence for a lifetime.

How it works

Use October 2 as your hook. A date gives people a reason to act now: "I'm aiming to hit $1,000 by October 2." Treat it like a small holiday. And donations are welcome after the hike too — past teams have found that photos from the canyon bring in a second wave from people who meant to give and forgot.

FAQ

Real questions from our past two Grand Canyon teams (October 2025 and March 2026) — answered so you don't have to wonder.

I can't make a Zoom call live — will I miss out?

Nope! Every team call is recorded and the link (with passcode) is emailed to the whole team afterward. Watch on your own time, then drop any questions in the WhatsApp group.

How hard is this, really?

Honestly: it's a near-marathon day on foot, and the demands are frequently underestimated by first-timers. You may not avoid all pain or discomfort — but you can absolutely prepare for it. We start conservatively to protect knees, pace as a team, and plan for 10–16 hours so nobody has to rush. Hundreds of everyday hikers cross the canyon every fall weekend; with the training plan and a strong team around you, you've got this.

I'm not an athlete. Is this for me?

This event is designed for hikers, not racers — and this team is exclusively women 50+. The 12-week plan is built to take a regularly active person to canyon-ready. If you can commit to the Saturday endurance hikes and stay consistent during the week, you belong here.

What happens if I don't hit $1,000 by the deadline?

When you signed up, you authorized your card to be charged the balance if your fundraiser is short at the internal deadline (Friday, October 2). If you need an extension or a fundraising pep talk, reach out to Angie before the deadline — we've made plans with teammates before and we're happy to help. Also remember your $100 registration fee already counts toward your total.

Do I pay anything for the guiding?

No — your guides volunteer their time so that every dollar raised goes to the mission. You're responsible for your own travel, lodging, food, and park entry.

What's the weather going to be like?

Two climates in one day. Rims in October: freezing-to-chilly mornings (30s°F) — you'll want your puffy, beanie, and gloves at the start. Inner canyon: highs around 80°F+ in full sun. Rule of thumb: the rim feels like Flagstaff, the bottom feels like Phoenix. The real forecast won't be readable until about a week out, so your guides will send a weather-and-gear call in WhatsApp and email as we get close, including whether anything on the gear list can stay home.

Where do we get water? Where are the bathrooms?

The flooding destroyed the pipeline, so the spigots are off and the park is trucking water in for residents and staff. Carry capacity for at least 3 liters, and 4 if you drink a lot or the forecast turns warm. There is water at Havasupai Gardens, and your guides carry filtration and treatment so we can take water there. South Kaibab has no water at all, which is normal for that trail. Toilets exist at the trailheads and at intervals along the corridor trails. Your guides will brief the team on current conditions in the final days before the hike.

Will I have phone service?

Assume no service once you drop below the rim. Your guides carry GPS satellite communicators for emergencies, and you can tell your people you'll resurface by evening. Consider downloading offline maps and podcasts/music before you leave wifi — and keep your phone in airplane mode to save battery for photos.

What if I get hurt or can't finish?

We hike as a team with two experienced guides, a group med kit, satellite communication, and emergency shelter — and we talk through contingency plans together on the final Zoom. The honest truth about the canyon is that there's no easy exit from the middle, which is exactly why we train, start conservatively, and take pacing seriously. Small stuff (blisters, hot spots, tweaky knees) we handle on the move; taping and trekking poles are your friends for the descents.

Do I need a National Park pass?

Yes — bring your America the Beautiful annual pass if you have one, or buy entry when you drive into the park (one entrance fee covers both rims for consecutive days).

Should I bring poles? Should I tape my knees?

Poles: yes, and Sunny treats them as mandatory rather than optional. They take real load off your knees on roughly 5,400 feet of descent, and she uses them on every hike with elevation change for exactly that reason: staying able to do this into her 70s and 80s. If you don't already hike with poles, get a pair now and use them on your training hikes so the rhythm is automatic by October. Sunny brings demo pairs for anyone who'd rather not fly with them (poles can't be carried on, so flying means checking a bag).

Knee taping: worth it before a descent this long. Sunny now tapes before a downhill canyon day herself. Here's the how-to video — practice on a training hike rather than the morning of. If you already wear a knee brace for workouts, bring it; if you've never worn one, race day is not the time to start.

What food should I bring?

2,000–3,000 calories of snacks you actually like — bars, gels, nuts, dried fruit, chips, candy. Variety matters: pack things that will still sound good when you're tired, hot, or cold, plus electrolyte tablets for your water. Test everything on training hikes. And leave a proper meal at your lodging for the finish, since restaurants may be closed by the time we're out.

Can I raise more than $1,000?

Please do! Overflow means more scholarships. Past teammates have set fun stretch goals (like $2,026 for 2026) and crushed them. The team that crosses together fundraises together — we'll cheer every milestone in the WhatsApp.

What about the night before — will I meet everyone?

Yes! We're gathering for a group dinner at the Arizona Steakhouse on the South Rim, Friday October 9 at 4:45pm Arizona time. Note that Arizona doesn't do daylight saving, so if you're coming from Kanab your phone may still read 5:45pm until it catches up. It's dark by 6 in October, so if you're camping at Mather, get set up before dinner. It's a lovely way to put faces to WhatsApp names before an early morning.

Questions?

Email Angie anytime at [email protected], or drop your question in the team WhatsApp once you're in — if you're wondering something, a teammate probably is too.
