I just finished my evening workout. I ended up doing a brick consisting of a 90 min trainer ride (WU, 5x15min as (5min @ 200 watts, 5min @ 225 watts, 5min @ 250 watts), 5min EZ) and a 15.4 mile run. It is amazing how much better I felt tonight. I ended up hydrating well over the course of the day and taking a 30 min power nap... I am sure the combination of the two had something to do with the change in my energy levels.
My runs are feeling better and better these days (knock on wood). :)
