Not at all . Great learning experience - going to go back and might pick the "ironman florida" course, I hear its very flat. Though I might take some time to setup a totally flat 40k ride so I can measure a reference 20 minute FTP and come back to measure progress over time. The hills throw off the readings... not so much the climbs but the decents. For true "course training" I'd rather be out on the road - I know balance and position are so extremely important I don't want to overlook them in any way.

For 20 minutes I'm certain I can get into the high 200's... if not 300. Note also that I have to ride 15 miles to get to this shop, no complaints IMO it makes the readings a bit more realistic.

The 32 miles from the shop to my friends house in the burbs after the above 41k was murderous though - particularly the last 6 miles since it was not only getting colder I was really feeling the pain.
