I was mostly satisfied with the blocks in training runs, but in the race environment they didn't work even if nutritionally they were a success. What foods do you use on long runs? Any suggestions for things beyond gels?
I did hill intervals once a week, and I've been doing them regularly for over a year. I warm up and then run up and walk down as many times as I can before either my form suffers or my run up is just a jog. Then I do a cool down jog. I love/hate them.
