I didn’t use TR as my main training for 3 Peaks in the end, but instead used HPTek’s intermediate training plan available from the event website.
Personally, i looked at the options available and decided to run with this plan, developed specifically for the event by a respected coach (Dr Stephen Lane), who is also one of the 8 hr wave leaders each year.
Not taking anything away from TR, i just felt more comfortable with the volume and specificity of HPTek’s plan. Having said that, i like to train indoors during the week, so for many of the weekday rides i looked for a TR equivalent or i created them in Workout Creator. During the weekend i stuck to the planned outdoor rides. As we approached the end, we were doing some big hours on the road. The other thing i did was to train on the GPX routes of the three major climbs using Tacx Desktop App. I am in New Zealand and couldn’t ride them myself, and the longest duration climb where i live is 20 mins, whereas Mt Hotham is 90mins plus.
So a bit of mix and match worked for me at my first go at the event. Got around in 8:46 and was stoked with that. If i wanted to prepare using TR more, i would use SSB 1&2, Sustained Power Build and Century, and supplement them with a long distance/hill repeats workout in the weekend if possible, and if you can’t get outside, then ride the GPX routes on the app of your choice.
On the day, sticking with the wave leaders of your targeted time is a great strategy for success. They know the right pace to achieve your goal. Working out the typical watts/kg you will need to do for the climbs to achieve this, and training on hills to sustain that level for 90 mins plus will help you start the race with some confidence.
It’s a great event, so enjoy the experience and the best of luck
