The paths close to my dwelling in Brighton are severely 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 whenever 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 vitality price of uphill working is increased, making it a difficult however probably rewarding sort 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 throughout 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 could 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 effectively 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 decreased 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 recommended working downhill could scale back threat of of Tibial stress harm.
A key level with each uphill and downhill working is the person response will fluctuate.
Velocity, gradient, step price and tissue load all work together and are influenced by method. For instance, a runner aiming to run quicker downhill could improve 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 probably improve peak load on the knee and Tibia.
Nonetheless, a extra cautious runner aiming to run downhill extra slowly could improve step price, taking brief, fast strides to manage the descent. Whereas this may improve loading cycles it could scale back muscle calls for and cargo on the knee and Tibia, particularly if pace stays low.

Medical utility
As method will fluctuate it’s finest to evaluate somebody working on the hills throughout gait evaluation if that’s a particular aggravating issue for them. Then you possibly can discover methods to assist, akin 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.
