Training for a 50 mile run in June. No time goal and expect to run / walk I.e. Run 5 minutes, walk 1.
My training is good in terms of weekly mileage (building towards 50+ miles a week) but I'm finding it hard to find time for long runs. My question is how much do long runs (over 2 hours) matter? If I'm running 4 half marathons a week is that ok or do I really need those 20 milers under my belt before the race?
