Interested in peoples views on the pro's and con's of my current training schedule. Monday to friday I am fitting training into my commute. This means:-
Start of day:
Home to station - 4 mile run
Train to London
Station to Work - 4 mile run
End of day: reverse the above.
Additionally, I'm running with a club 2 evenings a week (circa 6 miles on each occasion), and a longish run at the weekend.
I feel ultra fit, but am concerned that all these short bursts of energy are developing the wrong sort of muscle fibre... any thoughts? Do I need to change this routine?
