Today I did my first ever 10 mile TT! Seing as all organized TTs are canceled due to COVID-19 I figured I’d just do one on my own.
I’m currently in Sustained Power Build LV Week 3 and had Galena +1 on the menu. Was feeling good, so I figured I’d go for a 10 mile TT as the first interval and just see what happens after that. Needless to say I that left me pretty fatigued. So instead of the remaining 2x20min @95% I did 2x10min.
Thought I’d share the results of the TT and see what guys think are possible improvements:
Distance: 10 mile (16.1km) in 27:14
Speed: 22mph (35.5kmh)
Power: 237W (94% of upright FTP 252W)
Position: Road bike (Giant TCR) using clip on aero bars
Gear: standard road kit, no aero helmet/skin suit/over shoes
Tires: Schwalbe One V-Guard with butil inner tubes
Weather: about 20 degrees Celcius with a 10mph (17kph) NE wind
Road surface: 90% smooth tarmac, 10% somewhat smooth
Course profile: Flat, no road crossings or stopping lights
Note: had to slow down and go offroad once because a tractor was blocking the road.
Really stoked at the results. Didn’t expect to go this fast considering the wind and being in the middle of a training block. I even got a season power BP of 28 minutes @ 238W and that’s done in the aero bars. My upright FTP is currently 252W. So I held 94.4% of my FTP for 28min in the TT position.
This is my first Base/Build cycle using Trainerroad and I can honestly say the results so far have exceeded my expectations.
- Is holding ~94% of my upright FTP in the aero position for 28min considered an acceptable loss, or should I do more training in TT to lessen the gap?
- How much do you think I would could gain in speed on this course using lower rolling resistance tyres, latex tubes, over shoes, TT helmet and skin suit?
- What do you think of my pacing? Should I have maybe done more of a ramp up or down? Roughly first half was tailwind, second half was headwind.
