Blummin 'eck - a regular 40 miles a week ?
I'd be way too tired for anything if I was doing those kinda distances.
I think my highest mileage this year was 30 miles and that included running the darn Marathon. Most weeks would have been 18 miles or so, except when building for FLM, when I did get a few 30 mile weeks.
In fact before my 1.26 PB for the Chester Half I'd only done 26 miles spread over 4 weeks, but with about 110 miles of cycling and a very few runs on the treadmill.
I really think I'd go worse if I ran as much as I was expected to.
So doing a 10 mile interval session tonight then ?
