Can someone help me - I don’t understand how the 4dp / training load is calculated here. All the work was above FTP (and mostly above the target) but the MAP load is only 13%. My FTP is 218 and MAP is 254. I get it if 4DP is calculated from things only above my MAP but then that’s not the stated point of the workout. (Most of the targets were 230/240 and up to 260)
Any ideas?
I’ve complained about this since the beginning of the DTL calculations, MAP gets shortchanged.
So that workout should be mostly FTP - all the rest Intervals add up - but yeah there should be more MAP.
I think that MAP is the leftover 4DP, that load gets categorized in this order:
There’s also a time component to the calculation - if you do 5s sprints you can get NM or AC, but unless you stay perfectly in range for at least 30s or so you don’t get any MAP, so that workout doesn’t get much.
If you want to see something wild, this is what I got doing The Model on erg mode and hit all the targets:
It makes it real hard to get significant MAP DTL outside because if you pop above or below the range for a second, it the effort gets categorized as FTP and/or AC.
I’m guessing this, as my training this year has mostly been detraining 
but from what I see from your graphs makes me assume the biggest factor in calculating MAP for DTL is time without recovery. I’m thinking somewhat longer outdoor climbing efforts than Cygnet Coast or for indoor, maybe something AVDP?
It’s definitely more duration based than intensity based. I got more MAP load doing Costa Blanca: Cumbre del Sol (nee The Trick) because the intervals were 1 min long even though all the intervals were at 125% of my AC to try and set a new AC value.
Yeah - MAP is my limiter according to my profile so it would be good to see how much I’m working on it, so it’s tricky when it gets calculated last. Anyone from Wahoo can shed light on this?
I guess the good thing is that doing MAP workouts works even if the DTL calculations are wonky. It was also my limiter and I focused on it real heavy and it went up quite a bit.
That said, I think their general idea is good - MAP is about those hard unsustainable efforts. A couple of 20 second sprints isn’t going to make it better, but things like AVDP or 9 hammers might be best.
True. I’m doing the metric century plan as an off season prep so i get a bunch of different things like this. I guess the more time I spend between 230 and 280 the better for my MAP. DTL is only a number!
Yeah man go kill it!
Definitely try the new Pain Shake workout. It’s a very good MAP workout - 90sec intervals and the “recovery” is like high tempo so you’re working hard for the whole 9 min block.
Even though I was giving it grief above, The Model is also one of my favorites for the same reason- you work across the range of your power over threshold and the high recovery also forces more endurance.
Pairing structured metric century volume with high-intensity MAP sessions like AVDP creates a solid foundation for your upcoming season build
I have failed to link my outdoor rides with wahoo, so I don’t pay much attention to DTL, but I have been looking at Strava and training peaks stress loads, to sort out my trading and to prevent overuse injury. If I misunderstand your question, I apologize, but here goes:
I am not sure how wahoo calculates load, but I have read a little about MAP targeted workouts. The key part seems to be getting not just power but also hr above threshold for 15-20 minutes, which Nine Hammers does really well along with the 30/15 and 40/20 workouts (like Rue the Day) And you can really hurt yourself in The Bat if you bump the 4 minute interval target to 90+%MAP.
So perhaps that how DTL works? If your hr+power doesn’t stay above threshold long enough, then you aren’t pushing on MAP the boundary.
GCN ( former Sufferfest partners) has a video about 30/15s.
If you have a power meter, a garmin and strava, you can export the activity from strava (web, not app) and upload into the wahoo app. It works really well. Not much use if you don’t have a power meter on the outdoor bike though.
I think here because the time wasn’t above the MAP number, it didn’t recognise as MAP, despite being planned for MAP…I had the same with pain shakes, the target was 230, my ftp is 217 and MAP is 250) and 95% of the ride was set as FTP.
