Too early for top end training?
I have 40 mins to spare before breakfast on the turbo, is it too early in the season to be doing top end training e.g. 4min intervals where my bpm goes to 90-95% of mhr? I go on the road 3 times per week (weather permitting) in company which pushes me hard for 30-60 miles. I rarely do long steady miles. Last season I felt completely tired out by August after riding short distance TT's regularly.
