I did 2h@299w this tuesday and 20m@351w today so I’m guessing around 90-92%
91%, but wasn’t shooting for 2 hour power, so maybe 1-2% higher if I crushed myself, but I also train and race for endurance/>4 hour races.
79%
I have Gibraltar coming up but this made me go search out the extra 15 minutes of pain and I found Polar Bear and Polar Bear +1
I’m wondering how your power curve has changed? Most of mine as far as “shorter” endurance is from ramp tests, with sprints more likely to have happened outdoors (I was sidelined by injury for 4 months last year followed by lockdown so most of my outdoor rides are now both historic and without power data).
Having listened to the podcasts where they talked about using your strengths learning from your power curve, I wonder if it’s taught you anything about your longer endurance performance?
I just did 82% of my ftp for 3 hours, but it had a store stop does that count?
Maybe. What did you get at the store?
I had brought gluten free pancakes with Nutella to eat, they were warmed by the heat of my body in the jersey pocket. I basked in the sun like a large lion knowing that on the ride home with the tail wind I could provide fitness gifts to the whole group.
Nutella? Counts.
Pancakes on the bike are better with cake icing but I was fresh out.
Not shooting for 2h power, i was at 81%.
Interestingly my 3h is not that much lower at 78%…
I could have done with one of those on Sunday
I did 75 % on Saturday non stop for 2hours then 84% of the FTP on Sunday for 2hours. Then pop. Half a banana got me home and thankfully a tailwind. By then, 2hours later, I’d fallen to 74 % 
My 2 hour max power is the same as my 4 hour power, which was about 85% of my old FTP (did it just before my last rest week and FTP test). I have never specifically tried to go for 2 hours exactly…because nothing around me is like that (either 45 min to 1.5 hour climbs or 4+ hour massive Strava segments), but when I set that it was trying to do a solo 4 hour on the Uber Pretzel in Zwift.
But now you’ve given me an idea for a hard Zwift ride the next time the weather sucks 
Polar Bear +1 looks a good one to try.Much harder than outside as absolutely NO breaks 
One of my favorite TR workouts. I think I’ve only done the ramp test more than polar bear +1.
88% for me
87% for 2:13… middle distance relay triathlon.
I don’t feel that way as outside naturally will have more over threshold efforts, so I find inside workouts to be easier.
I’ve been using average power for the 2-hour % FTP, but if calculating off NP then its much higher. Here is a 98% 2hour-NP-to-FTP:
and a 99% 2hour-NP-to-FTP:
To my eyes it seems silly to use NP for these calculations. Using average power gives 88% and 91%. Those were selected using 2 hours on the PDC and you can see that first one only had 107 seconds of downtime which in my humble opinion was more than offset by ~8 anaerobic efforts.
About 89% for me
+51 watts. Tried to get the course record. Couldn’t.
