In my opinion, cross country skiing is one of hardest sports to train and compete for. My ignorance to this sport has definitely made me watch the Winter Olympics with my mouth wide open. Afterall, being a former elite track and field athlete, I thought nothing else but track. Training for track and field, I thought no other sport can even hang with us. But all sports have there ways of being hard to train for but very similar in mechanics. Every sport intertwines with each other. What sport do you think is the hardest to train and compete for and why?
