How to start

Find a hill that takes 20 to 30 seconds to run up at a firm effort. Warm up for 10 minutes, run up four times, jog or walk down to recover, then cool down.

How to progress

Add one repeat a week, or lengthen the hill slightly. Hill sessions are demanding, so do them once a week.

What the evidence says

Evidence: limited

We found no good trials on hill repeats specifically. The general case for hard interval training is in the fartlek evidence, and running uphill is a common way to add strength and power while keeping some impact off the joints. We have no reliable data on injury risk from hill repeats.

Take care: Hard hill running loads the calves, Achilles tendons and hamstrings. Build up your easy running first, warm up well and stop if a tendon is painful.

12-week starter plan

Once a week, after a good warm-up. Run up at a firm but controlled effort, then jog or walk back down fully recovered. Add one easy run in the week.

0 of 12 weeks done

Tick each week as you finish it; your ticks are saved on this device only. Repeat a week if it felt hard. Weeks 4, 8 and 12 hold steady so you can settle. This is a general plan, not medical advice.

Frequently asked questions

Do hill repeats make you faster?

They build leg strength and power, which can help running economy, but we found no trials comparing them with other training.

How steep should the hill be?

Steep enough to make you work, but not so steep you have to walk. A gradient of about 4 to 8% suits most people.

How many should I do?

Start with four. Add one each week up to about ten, only if you feel recovered.

Are they hard on the knees?

Running uphill is easier on the knees than running down. Take the downhill gently.
