The four phases

Weeks 1–3

Base

Build the habit and your aerobic engine with easy volume, short hills and strength foundations.

Weeks 4–5

Build

Longer mountain days and hill repeats, plus back-to-back runs for ultras: the bulk of the training.

Weeks 6–7

Peak

The biggest weeks: long runs with your race gear and fueling, and sustained climbs at race effort.

Week 8

Taper

Less volume, same rhythm: arrive at the start line rested and sharp.

Week by week

Monday to Sunday. Open a week to see each day; durations are total time.

Easy runs

Move them to your machine if you are coming back from an injury or want less pounding. The long run and the hills stay running: that is the specific work.

The training days

Mountain day

Your long run on trails with climbing, the key session of the week. Keep an easy, conversational effort, walk the steep climbs and practise your fueling.

Hills

Uphill work for climbing strength: strides, repeats or sustained climbs depending on the phase. Hard going up, easy coming down.

Easy run

Short, relaxed runs that add volume without fatigue. If you can’t talk, slow down. Being pure aerobic work, you can also do them low-impact on your machine.

Strength

Legs, hips and core: squats, lunges, step-ups and single-leg work that make you stronger on climbs and steadier on descents.

Strength training guide
Low-impact aerobic

Zone 2 aerobic volume without the pounding of running. The bike is only one option: the elliptical, a stair climber, a rowing machine or aqua jogging work too, each for a different goal.

Choose your machine
Rest

A day off or gentle mobility. This is when your body adapts to the training.

How do you do your low-impact aerobic day?

The bike is not the only way to add aerobic volume without impact. Pick the machine you use and the plan adapts every week, or leave it on “By phase” to follow our recommendation.

Go by heart rate. On a machine you are less used to, your muscles tire before your heart: stay in zone 2 by heart rate to make sure the work is really aerobic.

Match it to your goal. For climbing, prioritise the elliptical with resistance and the stair climber; for a break for your joints, the bike and aqua jogging are better.

Frequently asked questions

How long does it take to train for a 10K trail race?

Plan around 8 weeks if you already run three or four times a week. 6 weeks can work if you are already fit; take 10 if you are building up from less running.

How many hours a week should I train for a 10K trail race?

This plan starts at about 3 hours a week and builds to around 4.5 at its peak, with an easier week every fourth week so your body absorbs the work.

How long should my longest training run be for a 10K trail race?

About 1h 30m on trails with climbing, a few weeks before the race. You don’t need to cover the full distance in training: weekly climbing (up to 700 m+ at the peak) and consistency matter more.

What cross-training should I do for a 10K trail race?

One low-impact aerobic session a week, in zone 2 by heart rate. Pick it for your goal: the elliptical or a stair climber for climbing-specific work, the bike or aqua jogging to rest your joints, and a rowing machine to strengthen the back, shoulders and core you use on technical descents and with poles.

Do I need strength training for a 10K trail race?

One or two short sessions a week for legs, hips and core make you stronger on climbs, steadier on descents and less prone to injury. The plan keeps them light in the last weeks.
