Doing London and wondering how much training to put in.
Looking at some of the forums some runners are intending to put in 80+ miles per week. I could never fit in that mileage, even if I wasn't swimmming and cycling.
Aiming for sub 3h15m (=2*1/2 marathon time plus 10%) on 3 runs per week, so about 20-25 miles. I also do 3 swims and 3 cycles.
Any comments/suggestions welcome.
