Something all you athletes and habitual exercisers should really consider is an off season. What does that entail? Well it doesn't have to be anything earth shattering, it should simply mean an opportunity to change up your activities, and recharge you body and mind.
I've had quite the protracted road bike racing season this year. I started racing in March and have gone hard right up to the last week of September. I could tell I was feeling some mental fatigue as I was losing the desire to do workouts on the bike, and I love training on the bike. For me the off season means getting back into the gym. I'm doing some pretty focused and intense strength training for the next few months, and I'm taking October completely off of any structured cycling - riding only how and when I want to. I'm 7 days into the off season and already I feel great. I'm feeling more mentally fresh and starting to get excited for the upcoming winter training and chasing the lofty goals I've set for 2016.
All athletes, be they recreational, amateur, or professional need time away from their chosen pursuit. An off season doesn't have to be long, but I guarantee that time away will actually make you stronger both mentally and physically. Nobody can be at there best 24/7, so have some down time and then peak in your performance when in matters. The mind needs rest as well, and there is nothing like some time away to really get that motivation back.
Keep striving to excel!
