Well I probably broke every rule in the structured quality TR training book, but I got faster than when doing TR highly structured work indoors.
Here are the two workouts from Tuesday of the week posted above:
AM Commute:
Lambert Loop in the afternoon:
pretty high quality ~6.5 minute vo2max effort at 109%
Wake up the next day and another threshold effort for 24 minutes, then an hour of tempo at 85% on group ride.
Not saying its the best way to train, and I did have a lot of unplanned recovery days, but ultimately after months and months and months of doing that it produced results
