I ran a half marathon on June 29th, i done it in 2 hours 5mins. But i have done nothing since only eat, drink and sit on my arse. I plan on signing up for another race (10 Mile) to give me a goal. I feel i have lost all of my fitness and will be starting from scratch again. What are peoples toughts on this, have i lost all my fitness in the past 6 weeks? i was training for about a year up to the half marathon.
