The paths close to my house 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 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 increased, making it a difficult however doubtlessly 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 section 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 substitute as a high-intensity exercise if quicker operating is painful for the knee (which it may be as peak knee load tends to extend with velocity).

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 diminished operating downhill however with Tibial load there are some conflicting findings within the research. Van Hooren et al’s wonderful current paper reported elevated peak Tibial load with downhill operating, whereas Rice et al. (2023) reported decreased Tibial load and steered operating downhill could cut back danger of of Tibial stress damage.
A key level with each uphill and downhill operating is the person response will fluctuate.
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 is able to be anticipated to extend muscular calls for throughout load absorption, particularly on the quads and would probably 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 this can enhance loading cycles it could cut back muscle calls for and cargo on the knee and Tibia, particularly if velocity stays low.

Medical utility
As approach will fluctuate it’s finest to evaluate somebody operating on the hills throughout gait evaluation if that’s a particular aggravating issue for them. Then you may discover methods to assist, corresponding to taking quick, fast steps downhill to scale back knee load.
You could want to adapt your energy work too if hill operating is the aim. For instance, together with eccentric quads work for downhill and strengthening the glutes and hamstrings for the uphill.
