Noob Weekly Volume Question
I'm a distance runner but I'm transitioning to cycling. I'm training for two races this summer. They're both mens CAT 5 criteriums that will be about 25 minutes long from start to finish. I'm unsure of how many hours a week I should be cycling in order to be prepared to race when the day comes. So, how many hours/miles should the average CAT 5 competitor be putting in in order to be competitive?
