This race's powerfile is very interesting. Doing a big race like Lancaster brings into account two factors how easy can you go when its going easy? and How hard do you have to go when its going hard? Here is the basic data:

Entire workout (248 watts):
Duration: 3:17:58
Work: 2945 kJ
TSS: 267.6 (intensity factor 0.901)
Norm Power: 333
VI: 1.34
Distance: 133.247 km
Min Max Avg
Power: 0 1050 248 watts
Heart rate: 67 186 147 bpm
Cadence: 29 126 83 rpm
Speed: 0 69.4 40.4 kph
Pace 0:52 0:00 1:29 min/km
Crank Torque: 0 108.7 27.5 N-m

At first glance of this I noticed that the Norm Power was fairly high for an event over 3hrs long, or at least that has been my experience so far since this has been really my first year with power. But after breaking down how much time I spent in each zone I soon found out why.

I spent 1hr 39min in Level 1 (<205watts) 49% of the race with 44min's (22%) of that not pedaling! Not to shabby.

The part that makes racing hard is being able to make the efforts later on in the race and that is easier to do if you can conserve the energy you will need later. I tried going with some moves as soon as the early break was brought back, but the move went a lap later and I had already slipped to far back to make the break. So what makes the racing hard before the splits? Its all the hard efforts to make it to the important finally of the races. As shown when I looked at the amount of time I spent in Level 6 (>450 watts)

40mins (20%) of the race I spent at or above level 6. I found that to be a fair amount. Thats why races like this are tough because after a while it is hard to make these high substanable efforts. They surely will break up a race.

Thanks for analyzing,
Breeze On

Power data is super cool... impressive climb at the end. Keep the data coming. More people should publish this stuff!
