Trail race training blueprint
Prepare for wet forest trails, mud, and sustained climbing in southern Chile winter conditions.
At 20 km with 750 m of elevation gain, this is a fast, punchy distance where speed and hill strength both matter. At 38 m of vertical per kilometer, much of the course is runnable — the plan focuses on building your aerobic cruising speed while preparing you for the steeper sections. The official cutoff is 6 hours, so pace management starts from week one.

Courses use rainforest paths, coastal hills, muddy singletrack, and rolling approaches around Valdivia.
Late June in Valdivia can be cold, wet, and muddy, so gear and traction choices are important.
Swap concrete training days, or mark a day done/skipped without changing the race-specific template.
Calendar apps can take a few minutes to refresh subscriptions. The snapshot .ics is a one-time copy; the personal URL updates when this page saves.
Key sessions include route buttons that deep-link into the Planner with pre-filled distance + elevation filters.
The plan is scaled from the race profile, not a generic road-running template.
Training emphasis: rolling aerobic speed, moderate hill repeats, and disciplined pacing.
If your race has a time limit, this estimates the minimum average pace and whether your target finish time clears the cutoff.

At 38 m of vertical per kilometer, much of the course is runnable — the plan focuses on building your aerobic cruising speed while preparing you for the steeper sections. The official cutoff is 6 hours, so pace management starts from week one. This training plan adapts the 16-week structure specifically for 20 km with 750 m of elevation gain, scaling weekly volume and vert targets so your body is ready for race-day demands.
Shorter trail races reward aggressive pacing and strong climbing. The plan emphasises quality intensity — hill repeats, tempo efforts, and race-pace sessions — while building enough endurance to finish strong on tired legs.
The 16-week programme is divided into four phases designed around the specific demands of 20 km and 750 m of climbing:
At 38 m of vertical per kilometer, much of the Torrencial Chile by UTMB COLLICO 21K course is runnable. Training should emphasise aerobic cruising speed — tempo runs on rolling terrain, sustained effort on moderate climbs, and efficient flat-to-uphill transitions. The biggest risk on a runnable course is starting too fast; practice negative-split long runs to build discipline.
