I also have a incredible coach who works my build cycles around specific events. This season was my first back in 6 years so first 3 months were spent with base miles and intervals. Everything is based on heartrate. I work between 200 and 400 miles a week depending on what we are working on. I am just beginning a nasty build cycle for sprints and crits to get ready for nationals...let you know the results in 5 weeks
I ride full time so having a coach to organize my schedule so I just concentrate on which route to take makes life easier than I could do on my own.
