Its all very short term, symptomatic of the now society we live in, resting may help in 5 days time, but not in 5 weeks time. I'm not against rest, but for a young guy one day a week should be enough assuming the usual training loads. Older people, obviously more R and R.

But steady 10 milers, 1 min or so off race pace will really help change your physiology, trim you down, increase you running efficiency. For anyone only running 20-30 miles a week more quality running miles = an improvement in 95% of cases... not 20 min miling fell runs.. they maybe enjoyable but physiological benefit will be minimal compared to a flatter trail run with nice runnable hills.
he isn't talking about running 100 miles a week, how many of us can get anywhere near that!!!! Just an assumption but Im guessing probably less than half that mileage would be a better shout. If someone runs a light 25-30 mile a week, then you might as well wait a few days till the legs are recovered and then really cane the 10miles, like a tempo or fartlek. Anyway none of us are sports scientists, and I don't think even the most renowned sports people have a water tight answer, its all a bit open to conjecture
