Cardiovascular proficiency is a very underrated part of sailing. Last summer I bought my first road bike and was hooked instantly on the opportunity to change up how I train my cardio. Instead of long dreary hours on the spin bike or the erg I now am out on the open road. Cycling has long been touted as a very strong training mechanism for sailing especially laser sailing. It is great training for leg strength and hiking.
Look me up on Strava if you want to keep up with my training or check out some of these articles on cycling below:
