Athens Twilight 2012 vs Sunny King 2012 power and heartrate data

May 3, 2012 at 9:56 pm 1 comment

Well, the results are in, and below is this year’s side-by-side comparison of two very popular pro criteriums (Sunny King and Athens Terrapin Twilight). I still don’t know how to decide which race is harder … so y’all look at the data and make some comments about how you interpret it. Thanks! This year’s races were held on back-to-back weekends with Sunny King held in Anniston, Alabama on Saturday, April 21st at 7:30PM and Athens Twilight held in Athens, Georgia on Saturday, April 28th at 9:00PM.

Summary Data

		Sunny King	Athens Twilight
Time		1:30:14		1:41:19
Distance	41.6 mi.	47.6 mi.
Avg Speed	27.7 mph	28.2 mph
Max Speed	36 mph		36 mph
Avg HR		176		174
Max HR		187		189
Avg Power	269		245
Max Power	1013		1088
Placing		26th		20th

Heartrate Zones

		Sunny King	Athens Twilight
Zone 5 (175+)	0:58:45		0:54:04
Zone 4 (155+)	0:31:15		0:46:50

Some notes about the data … first, it was really windy for this year’s Sunny King criterium, which partially explains the higher power / lower average speed. But a bigger factor in the Watts vs Speed differences between the races is that in Athens you have a long stretch of the course where you rest … from the downhill going into Turn 3 all the way through Turn 4. The only place to rest on the Sunny King course is about 3 or 4 seconds as you brake hard into Turn #3.

Here are the power maps … note that for the Sunny King race there is a lot more time to warm up on the course so a lot of the purple lines are from my warm-up laps.

Here is a side-by-side on the lap data for the two races showing avg power, max power, and avg heartrate. Sunny King is on a slightly longer course so there is only 60 laps as compared to 80 laps for the Athens Twilight race.

    I’m going to go with they are EQUALLY as hard based on the power data. Really cool to look at the two side by side. Heck of a ride in both races Brian! You never cease to amaze me!

Long commute home Interesting time space thought - if you see this pic within a minute of me posting it, then I will be at the crest of the middle ridge. A little bit more challenging than normal getting this angle of my bike at the cliffs today.
