The six stages

Stage 1 — The Start

Stage 1

The Start

Start: Playa del Rey, QueposFinish: Rafiki Lodge

34.91 kmClimb +865 mDescent -758 mCutoff: 4:30 PM

Aid stations

Boca Naranjito · 13.8 kmLondres · 20.1 kmLos Campesinos · 30 km

Adventure runs almost all of Stage 1 — the one day the two races share nearly end to end. Same 2:30am alarms, same beach start at Quepos with the sun already high, same soft sand giving way to gravel and then dense, humid rainforest. Sharp little climbs, technical descents, and river crossings that cool you for a moment before the heat closes back in. The bodies aren't adapted yet and the day humbles everyone equally. It ends, like the long course, at Rafiki Lodge — a hard, honest introduction to what the week will ask.

Stage 2 — Welcome to the Jungle

Stage 2

Welcome to the Jungle

Start: Plaza Deportes Dos BocasFinish: Playa Dominical

16.31 kmClimb +128 mDescent -230 mCutoff: No cutoff

Aid stations

Hatillo · 9 km

The short day — and a welcome one. While Expedition climbs out of Rafiki and crosses the Savegre twice, Adventure joins near the midpoint at Dos Bocas and runs the gentler final stretch to the sea. There's still heat, still sand, still no easy miles — but the legs get a chance to recover and the spirit to catch up. Road 34, the estuaries, and then Playa Dominical, one of the best camps on the whole route.

Stage 3 — The Queen Stage

Stage 3

The Queen Stage

Start: Playa HermosaFinish: Marino Ballena

19.07 kmClimb +250 mDescent -250 mCutoff: No cutoff

Aid stations

Uvita · 14 km

While Expedition takes on the Queen Stage's riverbed, waterfalls and highland marathon, Adventure runs the coast, a long stretch from Playa Hermosa into Marino Ballena. Soft sand and compact sand, shaded sections ducking in and out of the trees, then back onto open beach with the Pacific wide open beside you. Offshore, the famous Whale's Tail sandbar marks the finish — shorter than the long course, but the same turquoise reward.

Stage 4 — Revenge of the Borucas

Stage 4

Revenge of the Borucas

Start: Cuesta del BurroFinish: Palmar Norte

14.12 kmClimb +520 mDescent -1,227 mCutoff: No cutoff

The plunge. Adventure starts high at Cuesta del Burro and drops toward Palmar Norte — fourteen kilometres but well over a thousand metres of descent, the most downhill day of the week. The Boruca hills fall away behind you, dirt roads and steep grass slopes hammering the quads on tired legs. Short on distance, long on descent, and a fast, lung-emptying run into the finish town.

Stage 5 — The Paths of Osa

Stage 5

The Paths of Osa

Start: SábaloFinish: Playa Ganadito

24.48 kmClimb +1,280 mDescent -1,350 mCutoff: PA3 · 3:00 PM

Aid stations

Guerra · 12 km

Into Osa. Adventure joins at Sábalo for the back half of the day's wild traverse — dense tropical jungle, roots and narrow singletrack, climbs steeper than they look. And it shares the race's most cinematic moment: the speedboat skimming the Pacific edge of the peninsula before the long arrival onto Playa Ganadito, where the whole race converges for the final night. Macaws overhead, howler monkeys in the canopy, in one of the most biodiverse places on Earth.

26.58 kmClimb +780 mDescent -833 mCutoff: No cutoff

San Josecito · 11.2 kmAgujitas · 23.5 km

Becoming a finisher. The same emotional finale as Expedition, a touch shorter — a loop out of Playa Ganadito at the wild edge of Corcovado and Bahía Drake. Gravel roads, flowing singletrack, river crossings and beaches under rising golden light. By now the legs are heavy and the feet tender, but every step is toward the arch and the medal. In 2026 two Adventure women crossed this final line in an exact tie, side by side — that's the spirit of this race. Arms raised on the last beach, friends at the line, a journey complete.

Know before you go

The gearbox system

One main bag (max 74 × 51 × 39 cm / 100 L) carries your whole week. You hand it to Rex Cargo each morning at 3:00–3:30 AM and it travels to the next camp — so everything you need on course (hydration, nutrition, sun protection) goes with you. The box itself isn't included — bring your own, or the organization can source one for a fee on request.

Cash & pulperías

Carry small colón bills (₡5,000–10,000; ₡500 ≈ $1). The route passes tiny family shops — a cold soda mid-stage is fast sugar and salt — and there are no banks on course. Get colones at the SJO airport ATM and break them into small notes before the race.

Aid stations

Every runner must carry at least 1 L of hydration. Stations have water, 226ers Hydra Zero, cola, fruit, crackers, pretzels, chocolate and salted chips — but no cups, so bring your own soft flask. The race works hard to keep aid stations as plastic-free as possible. Special dietary needs: supply your own.

Tents & camp comforts

Camp offers 1-, 2- and 4-person tents, assigned by availability — a solo racer may get a 2-person, two may share a 4-person, and companions can share a tent with their racer. Afternoon coffee and a daily foot-care service are included. Massages aren't included, and the official race photography is available to buy.

The return — "the 7th stage"

Day 7 is a water taxi from Ganadito to Sierpe (assume you'll get wet — seal your electronics), then a premium bus to San José. Runners reach the hotel ~3 PM but the gearbox arrives ~7 PM, so keep dry clothes and valuables in a small waterproof bag. Don't book a departing flight before Feb 21.

The base camp experience

Every evening, a full camp is standing before you arrive: your tent pitched by our staff, hot food from our kitchen, medical hands for your feet, and the kind of fireside camaraderie that turns strangers from twenty countries into friends for life.

What to pack

Plan for daily rain and humidity that lets nothing fully dry. Train with your full kit before you fly, and be ready to look after yourself between aid stations in the remote sections — that self-reliance is part of what you came for.

On your body — the race kit

Six stages of heat and humidity: nothing fully dries overnight. Pack as if every stage starts in yesterday's weather.

  • Lightweight, fast-dry shirts and shorts — enough for six stages
  • Fresh running socks for every stage — non-negotiable for your feet
  • Broken-in trail shoes with real traction (mandatory) — plus a second pair to rotate while one dries
  • Cap or visor + polarized sunglasses
  • Sport sunscreen SPF 50 and anti-chafe applied before every start
  • Buff or light neck gaiter — soak it at every river for free cooling

In your vest — carried every stage

Aid stations carry fruit, water, electrolytes and sodas — but remote sections demand self-reliance between them.

  • Running vest with ~1.5–2 L capacity (bladder plus soft flasks is the common setup)
  • Electrolyte tabs or powder for refills — sweat rates here surprise everyone
  • Race fuel you have practiced with — gels, bars or real food
  • Phone in a real waterproof case — not a ziplock bag
  • Small cash in colones (~$200 across the week) for sodas and snacks from local vendors
  • Trekking poles if you use them — steep climbs and river crossings reward them
  • Small whistle and emergency blanket — grams that matter in remote jungle

Your feet — the race within the race

Blisters are the #1 medical issue in multi-day racing (~78% of medical-tent visits at comparable events). The medical team runs daily foot care at camp; this kit keeps you moving between visits.

  • Blister kit: tape (practiced on YOUR hotspots), sterile needle, antiseptic, dressings
  • Foot lube or anti-chafe for long wet sections
  • Test your shoe + sock combo WET in training — river crossings start on Stage 1
  • Camp sandals — feet need air the moment you finish
  • Night routine: wash, dry thoroughly, air out — every single evening

In your camp bag — the trucks carry it

Your tent is pitched and packed by staff. Heads-up: dish, cutlery and cup are NOT provided at camp — bring your own.

  • Dish, cutlery and cup — not provided at camps or aid stations
  • Lightweight sleeping bag or liner, sleeping pad and small pillow
  • Sleep clothes + fast-dry camp clothes
  • Headlamp with spare batteries — race-week alarms ring well before sunrise
  • Ear plugs and eye mask — camp wakes early and sleeps social
  • Fast-dry towel, wet wipes and toiletries
  • Packable umbrella — camp shade and sudden showers
  • Dry bags or ziplocs to organize the bag — everything stays humid otherwise
  • Recovery extras: dehydrated meals, shakes and favorite snacks to supplement camp meals

Health & admin

Travel/event insurance covering adventure-sports competition and medical insurance with rescue + repatriation are mandatory.

  • Passport + printed copies of insurance documents
  • Personal meds: painkillers, anti-inflammatories, antihistamines, stomach remedies
  • Insect repellent and lip balm with SPF
  • Power bank — camp charging stations exist but get busy
  • International roaming or a local eSIM if you want signal where it exists
  • Swimwear — rivers, waterfalls and the Pacific are part of the experience
