Hill climb, power pacing plan

Here's the elevation profile:

[img]cycleiwakuni.comtom thumb zenitsuboprofile.jpgOpen ↗[/img]

Total distance - 7.408 km
Elevation difference, bottom to top - 523m
Max gradient - 15.45% for 143 meters, starting 533 meters from the finish
Longest gradient - 12.5% for 1526 meters

Overall average gradient - 7%

Here's my plan to get under 30 minutes:

3 minutes: 400w (600 meters)
3 minutes: 320w (941 meters)
2 minutes: 410w (340 meters)
2 minutes: 250w (downhill stretch plus a short 7% climb for total 722 meters)

Then... the pain
18 minutes: 340w (4.2 km)

Then... the real pain
50 seconds: 430w (15.45% for 130 meters)
2 minutes: 370w (last 270 meters)

(distances/math might not be exact, but I know the course well enough to know the end of each segment)

I have to do these numbers, or better. These numbers by computer calculations should net me a total time of 29 min 56 seconds. Not much time for forgiveness in there, but the plan is always to better the numbers on paper.

Personal best for this climb was 32 minutes, without any thought of pacing. Results tomorrow! 30 minutes will place me top ten, 32 minutes probably top 15.
