Ask any runner who has completed the Boston Marathon what the toughest feature of the race is and they’re likely to say the inclines. The Boston Marathon course is renowned for the cluster of climbs runners have to tackle in the second half of the race—with the most famous ascent being Heartbreak Hill between miles 20 and 21.
However, while the old adage “what goes up must come down” doesn’t always apply to point-to-point running events like the Boston Marathon, it’s true that runners spend a lot of time going downhill in the race, and it’s important that your training takes this into account.
