oh the guilt issue,isnt it a horrid wasted emotion!im endeavouring to have one no bike day a week,i tend to swim on this day and treat myself to a sauna,AND I STILL EAT WELL.before i didnt on rest days and then i found the next day i wasnt refreshed and replenished.i also plan proactive things to do instead.like spring cleaning!bigger dog walk,i duno,clean the car.........OR EVEN CLEAN YOUR BIKE
