Trek 5000. Sunny, cooler (low 70's at start, high 70's at the finish), lower humidity and mild NE winds at 5-7 mph, a gorgeous morning. Great HIIT workout with some good hill work thrown in, modified the route to include a water stop in Burlington. After a good warmup, started off with 5 x 20 sec spin ups with 60-90 seconds between efforts; 5 x 30 high speed efforts with 90-120 second rest; 2 x sitting stomps, all out from 10 mph to 25+ mph in high gear; 5 x 60 second high speed/cadence efforts with 3 minute rest intervals; 3 x sitting stomps, all out; several longer TT efforts at race pace, 20+ mph/high cadence, 1 x 4 minute, 1 x 6 minute, 1 x 8 minute, 1 x 12 minute. Finished off with the sprint down Meredith to the school.
