This is a bit different from the normal BT MPA images we see. A 100Km ride - very steady MPA - keeping well under TP and I pushed at the end to get inside 3 hours. PP peaked by 17 watts.
As I start riding my bike outside I think that will go up as I cannot really sprint on my turbo bike.

Tuesday I was feeling fairly strong after taking it easy for a week. I decided to go out a little harder and see if I could grab a breakthrough to refresh my numbers. I didn’t really have a strategy; just attack the hills and keep the pressure on. The result was a really fun ride and a gold breakthrough!
I still felt that my peak number was still a little low. So today, rather than change my planned ride, I decided to simply augment it with some good, solid, sprint efforts. Success! Bronze result for peak power.

Nice work! Breakthroughs are like a nice little pat on the back, reassuring you that you’re improving from your training!
After having had a nice fakethrough yesterday that pulled my signature down I got a sweet gold breakthrough in today’s race

I’ve been using Xert for a few months now and I gotta give kudos to the team for developing a pretty robust and flexible training framework. I’ve been riding harder lately since starting back at the beginning of the year so here are three breakthroughs from this month.
I need to try for some gold breakthroughs.

In the middle of a 100k road race. Remember the exact moment as I had to dig really deep over the top of a drag so as not to get dropped off the group!! It’s about as accurate a breakthrough effort as I have ever seen. I was very close to blowing up!!

This is my first breakthrough in about 4.Months. I was so focused on my events that I just could not find time to try for one (I did have 5 near breakthroughs over this period). The cool thing about this one is it came 2 days after completing a 10,000 ft continuous climb in Maui to the top of Haleakala volcano…. Which means I could have done more if I was fresh

Great work Randall! Which decay method were you using during that time? Do you feel that the signature was underestimated?
I was using slow but switched to moderate decay after derating my ftp due to weight loss. I had several challenges during this period. Loss of weight (12lbs-intentional) and manually adjust TP down by 15 watts (feel) as a result-not finishing sessions , 5 events (last 2 being the target events), learn new skills (gravel event). I guessed my signature was low but frequency of training, intensity and ramp training load did not provide an opportunity for a breakthrough effort. I guess with my events completed and on vacation, I could throw caution to the wind and put the hammer down without having to worry about recovery and having enough energy for the next sessions.

Anotha’ one!
I was doing some 30/15’s with EBC on my Thursday interval route. When I was heading out, I wasn’t planning to go all-out for a Breakthrough, but couldn’t help myself once I looked down and saw my MPA below 500 W

So to answer your original question I believe my new TP is underrated for climbing by 3-5 watts but is probably correct for flats and TT

Two weeks off-bike due to illness and after a week of easy riding decided to do a BT effort indoors using “Xert Fitness Test for Breakthrough Version 2”. I think I left some on the table, which is fine, not trying to ruin myself right now anyways!

Gold BT on a outdoor ride up a monster hill. Very happy about this as I was worried I was losing fitness because I have been riding less for the last 6 weeks. My new FTP is lower than my peak from last year but my watts/KG is at a new peak because of weight loss.

Went in pretty rested intending to test my signature and get a BT. Got a silver, although the app maybe faked me out a bit and told me I’d gotten a BT much earlier than I actually did, I think.
I switched to slope for the last segment as per directions for the “Under Pressure” workout, which allowed me to keep going beyond what the workout was “drawn” to do. I think I botched the directions a bit, and I started the sprint too early though. I might have benefited from staying at 125% TP for longer. Instead, I started sprinting as soon as the last bit of higher difficulty burst interval occurred and then held the sprint as long as I could.
Overall I really liked this workout. It had been a month since my last BT and wanted to tune up my signature so it worked great for that.

Have been doing the Under Pressure protocol (ish) outside for BTs this season, and my signature was getting stale. Also have had a month off of serious training, with 4 weekends of partying/weddings. In that time my CP(calculated) went from 345 to 332 on slow decay and 3-5hrs/wk without any structure.
So I was very pleased with yesterdays ride home from work. I also rode in to work in the morning, 55mins at a tempo/sweetspot intensity, into a headwind, pressed for time 
Do I need to use an even slower decay model to reflect this in the future?
