So far, having managed to keep pretty much on track with the 10-12 hours a week,three or four sessions a week of 3 hours will do it.(I work split shifts for only 3.5 days a week)
I never never get hung up on distance during training.Time on your feet is all that really matters, you will move as fast as you want anyway...
Instead of making one run extra long, I kind of stuck with the two's and three's, and threw in a couple of double days by getting up @ 5:30 for 1/2 hour dash to Mt.Doug and back.Not quite "a two hour blast of the 'hood", but doubleing up keeps your metabolism pumping and teaches you many things about yourself..and about healing up quickly!
As for cutting down on the caffeine,I drink it strong and black twice a day from freshly ground bean, no sugar no nothing, just for the taste(single cup filters are the best!) I've cut out coffee as a dessert.
I have mannaged to race a fair bit this past winter, with two trips to the States, the DV, and a Marathon...I should be in good shape for Arizona in November, for my 100M.
The rest of my race card will have to fit in under my November training, but it's all good....
Oh, yes, and I'll try to get to the gym twice a week.
