Interesting about the feeling good and using it..

I tend not to.. Normally I do hard efforts, or hardish on Tuesdays and Thursdays, that's normally track reps, say 5x1k, 8x8's, or hills reps, and then either longer reps, 1 mile to 2k or tempo runs, 4 miles at 1/2 marathon pace on Thursdays. If I feel good Wednesday I'd still run the session I had planned.. which is normally 10-14 miles on road or trail at something like 1 min off my marathon pace.. maybe a tad faster.. I always struggle to work out what pace to do those runs, and was told 45s-1min off my current marathon pace... high 6's which feels comfortable.

So you reckon if you feel good you could so do another hard session again? Naturally I've always avoided back to back sessions..

I suppose I also come from a regimented football/rugby background when hard training was always Tuesday/Thursday play at the weekend.. whether you felt like it or not and that sort of still dictates my approach..
