i went in early to work this morning, so i'd have time to run a bit further at lunch time. i decided to try to simulate trail running as much as i could since this saturday's pi-day river rotation half marathon will be a trail race. i ran on gravel and grass as much as i could, running along the edges of the streets and the highway. i also tried to stay well beneath my redline and felt pretty good most of the time. i just need to run about nine miles more now and i'll make it to the finish line.
