Hill Training for Runners: Repeats, Strides and Planning
By anystride · Updated November 6, 2026
General training information. Not independently reviewed by a named clinician or sports dietitian.
Hill sessions add uphill running to a training week. They can be useful for practicing hills or varying harder work, but they are not automatically safer than flat intervals and do not guarantee faster racing.
What does the research show?
Barnes and colleagues studied different uphill programmes in 20 well-trained runners over six weeks. They reported improvements in 5K time-trial performance across the programmes, without one clearly optimal intensity for performance. This small study does not establish a best beginner workout or prove that hill training prevents injury.
Hill repeats and short uphill efforts
Longer repeats are a demanding session with recovery between efforts. Short uphill accelerations are briefer, but still add load and can produce fatigue. Choose the session your plan calls for rather than adding hills because they appear to be free extra training.
A cautious way to try hills
If you are already comfortable with regular running, try a few short, controlled efforts on a gentle, predictable slope, with ample walking or easy recovery. This is a practical example rather than a tested prescription. Start with less than a full hard session and review how you feel afterward.
- Warm up with easy running on a suitable route.
- Use effort rather than flat-ground pace to guide the uphill.
- Keep the descent controlled and watch footing and traffic.
- Stop if pain changes your stride; get advice for persistent symptoms.
Fit hills into the week
Count sustained hill repeats as harder running and leave recovery around them. There is no universal once-a-week requirement or fixed point when every runner should stop doing hills before a race. Consider the terrain of your event and the other work in your plan.
Using a treadmill
An incline treadmill is an option for uphill practice, but it does not reproduce outdoor conditions exactly. Returning the incline to zero gives a level recovery, not downhill running. Change speed and incline gradually using the machine’s controls; short fast efforts may be impractical on a slow-adjusting machine.

Frequently asked questions
Do hills help with flat road races?
Uphill training has shown performance benefits in a small study of trained runners, but the size and transfer of any benefit will vary. It is an option within a programme, not a guaranteed shortcut.
How steep should a training hill be?
Choose a slope where you can run with control and recover without awkward footing. There is no universal ideal percentage established by the evidence cited here.
Should beginners do hill repeats?
Beginners can establish comfortable regular running first. Walking steeper parts of a route is reasonable; there is no need to add a dedicated hard hill workout immediately.
Can hills replace track intervals?
They can be an alternative harder session when that fits the plan. They are not interchangeable for every purpose, and lower injury risk should not be assumed.
