Buy intervals.icu
I signed up to TrainingPeaks to continue to use indieVelo (Virtual), which is a good application.
However, I'm sorry to say TrainingPeaks falls into the 'meh' category along with majority of cycling performance applications. I've used/tested most packages my general criticism, is that they appear to be designed by non-cyclists. Calendar and charts are cluttered and confusing, personal 'virtual' performance management is difficult.
I would consider remaining with the application if it was useful, but sadly the decision will come down to price (and ethics) between other virtual applications.
TrainingPeaks should consider buying intervals.icu. Which is by far (!) the best analysis tool available.
