I used TrainerRoad last year to prep for a XCO Marathon 100km race using a high volume plan with gym on my off days. Not perhaps as recommended but with the forum and podcast to back everything up, it went super well. Saw an FTP increase by nearly 100W in 29 weeks. Race went to plan and did it in about 6 hours. Couldn’t recommend it more (and do so to anyone who will listen).
This year, my family gave me an entry for a new 160km XCO race over the same sort of terrain. I started two and a half months earlier but went for a mid volume plan. With the new tweaks associated with all the machine learning stuff, I notice the workouts are so much easier than last year. Not just subjectively - I never failed any last year but when I look back at their ratings they really are a world apart e.g., at this time last year I was doing Sweet Spot 8.9, this year I dont even get close (more like 4.3) and feel like I’m cruising.
Given how well things went last year and that this race will be essentially twice as hard, I’m getting a bit of a crisis of confidence in the new plans. Any reassuring thoughts? Should I revert back to high volume?
