The paths close to my dwelling in Brighton are critically hilly. A lot so, that a few of the hardest climbs have names! My favorite/ nemesis is ‘the snake’, so referred to as as a result of it winds on and on. Simply while you assume you’ve reached the highest you flip a bend and discover one other lengthy incline!
Alongside being a troublesome exercise, coaching on the hills considerably alters how we run so let’s discover this.
Uphill working
The power price of uphill working is increased, making it a difficult however probably rewarding kind of coaching. That is largely because of the elevated work of driving the physique up the hill. Because of this, we see a rise in exercise within the quads, calf, glute max and hamstrings throughout the propulsive part of working.
Uphill working tends to extend load on the Achilles tendon and Tibia however decreases it on the Patellofemoral Joint. So we could recommend to cut back uphill working in these with Achilles ache or Medial Tibial Stress Syndrome (MTSS), particularly if painful.
Nonetheless, with Patellofemoral ache, if it’s nicely tolerated by a runner we’d recommend persevering with these uphills runs. They could be a helpful alternative as a high-intensity exercise if quicker working is painful for the knee (which it may be as peak knee load tends to extend with pace).

Downhill working
Working downhill tends to extend patellofemoral joint stress, so if the runner in our instance above is doing hill repeats it could be higher to run up and stroll down. ITBS additionally tends to be aggravated by downhill working.
Peak Achilles load is lowered working downhill however with Tibial load there are some conflicting findings within the research. Van Hooren et al’s wonderful latest paper reported elevated peak Tibial load with downhill working, whereas Rice et al. (2023) reported decreased Tibial load and recommended working downhill could cut back threat of of Tibial stress harm.
A key level with each uphill and downhill working is the person response will differ.
Pace, gradient, step fee and tissue load all work together and are influenced by approach. For instance, a runner aiming to run quicker downhill could enhance stride size and use a low step fee. This may be anticipated to extend muscular calls for throughout load absorption, particularly on the quads and would possible enhance peak load on the knee and Tibia.
Nonetheless, a extra cautious runner aiming to run downhill extra slowly could enhance step fee, taking quick, fast strides to manage the descent. Whereas it will enhance loading cycles it could cut back muscle calls for and cargo on the knee and Tibia, particularly if pace stays low.

Scientific utility
As approach will differ it’s greatest to evaluate somebody working on the hills throughout gait evaluation if that’s a selected aggravating issue for them. Then you may discover methods to assist, similar to taking quick, fast steps downhill to cut back knee load.
Chances are you’ll want to adapt your energy work too if hill working is the objective. For instance, together with eccentric quads work for downhill and strengthening the glutes and hamstrings for the uphill.
