Got those 2x20 intervals in today at a beautiful park trail. Something of a trade off between here and my local route, I have to slow down for tunnels and such on the park route, but don't have to stop for any traffic lights. In either case, I think I pushed plenty hard enough today, what with me praying for a flat tire or broken spoke for the last 5 mins of the second interval!
