I’ve started noticing that I consistently have trouble with workouts that mix FTP and MAP targets in a single interval. My rider type is Pursuiter. My MAP is definitely high for my FTP. FTP 239, MAP 319 (80W difference). And that spread was even bigger at one point on early in my days of SUF at about 215/300 (85W) and 205/275 (70W).
I actually don’t have issues with workouts that have MAP only based intervals, even something like The Chores that starts with MAP intervals with short recoveries and ends on an FTP interval is ok. They are challenging, but I feel I can do them. And the workout feel as difficulty I’d expect given the power profile and Intensity Factory. The same with Attacker that ramps up from an FTP interval into a MAP interval is ok. However, intervals like you find in The Rookie, Defender (2 minute MAP start into 8 min FTP target), or a few of the intervals in The Omnium where it’s jumping between FTP and MAP just crush me. Usually I complete the workout with the targets, but sometimes I can’t. I’m wondering if the large delta between my FTP and MAP is causing those intervals to actually be harder than they should. For example in the beginning of the intervals in Defender the text on the screen says “A little above FTP” for the MAP Block. But is 286W a target “a little” above FTP when my FTP is 239? Are those workouts hitting harder than they should be since the interval as a whole ends up being at or above my FTP when I assume it should be a little below?
In any case, I’ve only failed about 4 or 5 workouts on the Sufferfest since I started using it 6 months ago, and they’ve all had intervals like that. The Omnium, The Rookie, There is No Try . Amazingly I did finish the 9 Hammers by some miracle. I’ve nearly failed Defender twice even though it’s not normally considered one of the more challenging workouts. Generally I get to the point of total failure/can’t go pedal anymore then back off the wattage targets for both FTP and MAP. But I wonder if I should start lowering the MAP targets right from the start on those workouts now.
