This season for me has been kind of a disappointing. I decided after two seasons of riding and a couple of races thru out the two years that I would race a local 10 race 1 hour long hair scramble series in the novice class for my third year riding a dirt bike. I am almost 30 year have 2 year old son and work a job that demands a lot of hours. So having time to train, ride, sleep & rest can be challenging. Anyways my season has gone like this start training late 6 weeks before the season , got the flu 4 weeks before the season, started training, 2 weeks before the season, got a bad cold the week of the first race finished mid pack. Started training again placed top three next races and improving each race. Worked 3 70 hr weeks in a row and got cold that carried over 2 races both resulted in mid pack finishes. Basically I have the speed win the races . I ussually lead for the first half to 3/4 the thing that is holding me back is my endurence. I cant seem to stay heathly long enough to build up my endurence. What should I do to stay heathy.
