In this quick video I am sharing my opinion and hard-learned lesson on why it's so important to maintain fitness you've gained. It's really-really hard to gain it all from ZERO, so don't lose everything by simply stop riding. You don't need to do much to maintain it. Just key sessions with some efforts. Overall - 6-8 hours a week would be plenty. My situation was a bit different, as I was injured and now I am learning how much fitness I lost in almost 3 months. So, if you are tired, take a break (short one - 3-4 weeks will be enough), but don't quit, you will regret it almost 100%:)
