It'd be really nice to be able to re-label intervals.
Rather than interval1, interval 2, etc... being able to label them as: warmup, cooldown, ilt, tempo, etc. Freetext with maybe a 20 character limit.
This feature was implemented with the last site update we did a few weeks back. Thanks!

Good news, we already have this on the development to-do list for 2011. This feature will behave just like marking up intervals behaves in our WKO+ product (if you are familiar with that), so you will be able to rename existing intervals as well as highlight a section of the graph and label it anything you want. Glad to hear you are looking forward to this feature coming to TrainingPeaks.com online accounts. Thanks for the suggestion!
