70.3 is May 16th and IM is August 22nd. The 70.3 isn’t all that important, but my weak point is endurance so don’t wish to curtail the longer training sessions leading up to it.
My original plan was to carry out the 70.3 training plan, take a rest/recovery week and then launch into the IM plan which would work out around the week before the race specific phase of the plan. Although would this approach bring about the risk of over training?
If its any help, I use a Garmin forerunner 735xt and all of the workout runs are in the training calendar once synced. When the workout is selected the Garmin will prompt you with details of each interval (time and target HR – if using HR plan) with an audible cue when each interval is finishing. Once uploaded, this is shared with Training Peaks (to compare against plan) and Strava (if you use it).
Just to add to this, my FTP both indoor on the turbo and outdoor are identical (280w). However, my HR tends to be lower indoors than outdoors. I assumed it was down to outside variables such as wind resistance, elevation, bike handling, rolling resistance, etc.
