Trail 100 Andorra by UTMBOrdino, Andorra🇦🇩

• •The organiser lists 105 km; the published GPX measures 103 km. The organiser lists 6800 m of climbing; the published GPX measures 6232 m. The technical course notes use the published GPX measurement.
• •This course reaches 2892 m. At the high-point coordinate, the same week historically ran 3°C to 11°C. Typical daily maximum wind was 11 km/h, reaching 22 km/h in the sample. This is climate history, not the race-day forecast; keep the shell accessible if race week looks similar.
• •Sunset is 21:31 and the finish cut-off is 16:00. A runner using the full time allowance spends the final 8 hours 45 minutes in darkness.
• •Get the headtorch out before sunset and keep spare batteries or a power bank dry and immediately accessible. A spare buried at the bottom of the pack is not an emergency spare.
• •Check reflective course markers regularly in the dark. If the markings disappear, stop moving forward, return to the last marker and confirm the route against the GPX or organiser app.
• •Poles are strongly recommended for this profile. The course averages 61 m of gain per km and the longest climb averaging over 5% runs 16 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.
• •The climbing is stacked into the first half. Start easy; even with less climbing later, the descents and accumulated fatigue still have to be managed.
• •25% of the course is steep descent. Increase your cadence instead of braking, or your quads go early.
• •Arrive early for the altitude. The course tops out at 2892 m, and coming up from sea level on race morning costs you more than any training block gains. Get to the area a few days ahead and let your body adjust.
• •The altitude is not a single summit: about 71 km of the course sits above 1800 m, 20 km above 2400 m. The longest unbroken stretch up high is 29 km and the high zone spans roughly km 43 to km 72. About 78% of the total climbing happens in that thin air, so recalibrate your effort to the altitude, not the gradient alone.

Aid stations

• •The longest stretch between official aid stations runs from Coll de la Botella (km 24) to Life Base 1: Parc Central - Andorra La Vella (km 39): 15 km. Top up at Coll de la Botella and size what you carry to the expected duration and your own drinking rate.
• •Drinks only, no food, at Refugi Fontverd (km 46). Loosen the flask caps on approach; with no queue, refill and leave in 20-30 seconds. Carry the food you will need from the previous station.
• •Hot food is served at Coll de la Botella (km 24) and Life Base 1: Parc Central - Andorra La Vella (km 39) and 2 more. If your stomach and race plan call for it, make this a deliberate 3-5 minute stop; do not sit down simply because hot food is available. Restart gently and let your stomach settle before lifting the effort.
• •Food is available at Refugi Pla de l'Estany (km 11) and Comapedrosa (km 18) and 3 more. Decide what you need before reaching the table; without a planned special task, collect food and fluids and leave within 60-90 seconds. Finish eating on the next calm, suitable section.
• •Drop bags at Life Base 1: Parc Central - Andorra La Vella (km 39) and Life Base 2 - Hotel Pic Maià (km 64). Write down the equipment and food you expect to replace before the race so the decision is already made when you arrive.
• •Crew support is permitted only at Life Base 1: Parc Central - Andorra La Vella (km 39) and Life Base 2 - Hotel Pic Maià (km 64). This is not the same as a drop bag: plan equipment and food hand-offs around these stations, then verify wristband, bag and transport rules with the organiser.
• •The last aid station is Refugi Sorteny (km 95), leaving 10 km to the finish. After that you are on what you carry.
• •The heaviest leg runs from Ordino (km 0) to Refugi Pla de l'Estany (km 11): 11 km with 980 m of climbing. Treat it as the slowest part of your day and get your food out before it.
• •Medical support is available at Ordino (km 0), Coll de la Botella (km 24), Life Base 1: Parc Central - Andorra La Vella (km 39), Life Base 2 - Hotel Pic Maià (km 64), Pont Tibeta (km 85), Refugi Sorteny (km 95), and Ordino (km 107). If something is wrong with your feet or your stomach, deal with it there rather than pushing on.
• •About 2 km after Refugi Pla de l'Estany (km 11), a roughly 250 m section averaging 45% begins. Choose food you know you digest easily and fill the bottles, then enter the climb at a controlled effort.
• •The overall cut-off is 34h, including all checkpoint stops. Build the plan around the official leg budgets below, not a flat-course average pace.
• •Relative to distance and climbing, the tightest official time budget runs from Life Base 1: Parc Central - Andorra La Vella (km 39) to Refugi Fontverd (km 46): the official time budget is 2h 15m for 8 km and 807 m of climbing. Station stops come out of that same budget, so do not enter the leg already behind schedule.

• •The climbing starts the moment you leave Canillo (km 49): the steepest roughly 250 m section averages 28%. Choose food you know you digest easily and fill the bottles, then begin the climb under control.
• •The overall cut-off is 21h, including all checkpoint stops. Build the plan around the official leg budgets below, not a flat-course average pace.
• •Relative to distance and climbing, the tightest official time budget runs from Start to Coma Arcalis 1 (km 15): the official time budget is 3h for 15 km and 1037 m of climbing. Station stops come out of that same budget, so do not enter the leg already behind schedule.
