The paths close to my house 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 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 greater, 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. Consequently, we see a rise in exercise within the quads, calf, glute max and hamstrings in the course of the propulsive section of working.
Uphill working tends to extend load on the Achilles tendon and Tibia however decreases it on the Patellofemoral Joint. So we might recommend to scale back uphill working in these with Achilles ache or Medial Tibial Stress Syndrome (MTSS), particularly if painful.
Nonetheless, with Patellofemoral ache, if it’s properly tolerated by a runner we’d recommend persevering with these uphills runs. They could be a helpful substitute 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 current paper reported elevated peak Tibial load with downhill working, whereas Rice et al. (2023) reported decreased Tibial load and advised working downhill might cut back danger of of Tibial stress damage.
A key level with each uphill and downhill working is the person response will differ.
Pace, gradient, step price and tissue load all work together and are influenced by method. For instance, a runner aiming to run quicker downhill might enhance stride size and use a low step price. This may 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.
Nonetheless, a extra cautious runner aiming to run downhill extra slowly might enhance step price, taking brief, fast strides to regulate 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.

As method will differ it’s finest 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, corresponding to taking brief, fast steps downhill to scale back knee load.
You could want to adapt your power work too if hill working is the purpose. For instance, together with eccentric quads work for downhill and strengthening the glutes and hamstrings for the uphill.
