The paths close to my dwelling in Brighton are significantly hilly. A lot so, that among the hardest climbs have names! My favorite/ nemesis is ‘the snake’, so known as as a result of it winds on and on. Simply if you suppose 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 operating
The power value of uphill operating is larger, making it a difficult however probably rewarding sort of coaching. That is largely as a result of 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 in the course of the propulsive part of operating.
Uphill operating tends to extend load on the Achilles tendon and Tibia however decreases it on the Patellofemoral Joint. So we could counsel to scale back uphill operating 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 counsel persevering with these uphills runs. They could be a helpful alternative as a high-intensity exercise if sooner operating is painful for the knee (which it may be as peak knee load tends to extend with pace).

Downhill operating
Operating 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 operating.
Peak Achilles load is lowered operating 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 operating, whereas Rice et al. (2023) reported decreased Tibial load and instructed operating downhill could scale back threat of of Tibial stress damage.
A key level with each uphill and downhill operating is the person response will fluctuate.
Velocity, gradient, step fee and tissue load all work together and are influenced by approach. For instance, a runner aiming to run sooner downhill could enhance stride size and use a low step fee. This could 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 regulate the descent. Whereas it will enhance loading cycles it could scale back muscle calls for and cargo on the knee and Tibia, particularly if pace stays low.

As approach will fluctuate it’s finest to evaluate somebody operating on the hills throughout gait evaluation if that’s a selected aggravating issue for them. Then you possibly can discover methods to assist, equivalent to taking quick, fast steps downhill to scale back knee load.
It’s possible you’ll want to adapt your power work too if hill operating is the purpose. For instance, together with eccentric quads work for downhill and strengthening the glutes and hamstrings for the uphill.
