I completed NY marathon in Nov '10 which was my first marathon and i ran it quite comfortably. I am now training for Paris marathon in April and my training runs are hell.....with my legs feeling really heavy right from the first mile. I'm def not over training and do approx 3 runs a week including a long run. i gave up after 6 miles yesterday in my planned 15 mile run as my legs ached and just wouldn't work!
Any advice on how to get rid of this heavy legs feeling as its killing my long runs off at the minute
