The paths close to my dwelling in Brighton are severely hilly. A lot so, that a number 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 once you suppose you’ve reached the highest you flip a bend and discover one other lengthy incline!
Alongside being a tricky 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 doubtlessly rewarding sort of coaching. That is largely as a result of elevated work of driving the physique up the hill. In consequence, 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 scale back uphill working in these with Achilles ache or Medial Tibial Stress Syndrome (MTSS), particularly if painful.
Nevertheless, with Patellofemoral ache, if it’s effectively tolerated by a runner we would 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 velocity).

Downhill working
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 working.
Peak Achilles load is decreased working downhill however with Tibial load there are some conflicting findings within the research. Van Hooren et al’s glorious current paper reported elevated peak Tibial load with downhill working, whereas Rice et al. (2023) reported decreased Tibial load and instructed working downhill could scale back danger of of Tibial stress damage.
A key level with each uphill and downhill working is the person response will range.
Pace, gradient, step charge and tissue load all work together and are influenced by method. For instance, a runner aiming to run quicker downhill could enhance stride size and use a low step charge. This might be anticipated to extend muscular calls for throughout load absorption, particularly on the quads and would doubtless enhance peak load on the knee and Tibia.
Nevertheless, a extra cautious runner aiming to run downhill extra slowly could enhance step charge, taking brief, fast strides to manage the descent. Whereas this can enhance loading cycles it could scale back muscle calls for and cargo on the knee and Tibia, particularly if velocity stays low.

Medical utility
As method will range it’s greatest to evaluate somebody working on the hills throughout gait evaluation if that’s a selected aggravating issue for them. Then you possibly can discover methods to assist, comparable to taking brief, fast steps downhill to scale back knee load.
You could want to adapt your energy work too if hill working is the aim. For instance, together with eccentric quads work for downhill and strengthening the glutes and hamstrings for the uphill.
