Your concern must be based on something - personal feelings, physiological signals, hesitations, anxiety during high stress situations, lack of motivation to keep on pushing, lower benefit/risk ratio, less personal gain etc. Whatever it may be only you are in a position to answer that question. I am also faced with a similar dilema every race season and I'm already planning how to improve my performance this coming season. I enjoy riding and occassionally testing myself against other riders in my category. I hope to confront this dilema only once a year at the end of the season.
