Chessyman Race Rehearsal #1

The Chesapeakeman course is close enough to home that we loaded up the family truckster and headed south for the day. The wife and kids enjoyed the last day of summer vacation on the bay while I recon’d the course. This ride is totally flat and, coming from hilly country, I had no idea what my ride time would be. I wanted to get an idea in advance of race day.

The wide open roads and abundant wildlife scenery make for a beautiful ride. The course is set up as a 17-ish mile out & back followed by two 47-ish mile loops. Perfect for setting up a pacing strategy. I used the out & back as warm-up and then attempted to negative split the two loops.

In layman's terms I had a good day, finishing in 5-1/2 hours with a negative split. The data reveals I could have actually pushed harder and still have a reasonable chance at running a respectable marathon. So for my next rehearsal in 3-weeks, I'll focus on giving it a little more gas.

Here's the raw data for any geeks checking in:

Goal watts = 182, based on 70% of 260w FTP.

Nutrition

Drank as much water as I could carry.

Successes
• Negative split with strong finish.
• Ability to focus on loop #2 (did not take caffeine).
• First long ride in new position. Felt fine. Big difference from previous position!
• Lowest TSS ever for 112 mile ride.

Room for Improvement
• Confidence to ride at higher watts on out & back and loop #1.
• Polar transmitter being serviced. Need HR data on RR#2 in 3 weeks.
• Gut was sick on run… Overheating, dehydration, ran too hard???
• This rehearsal focused on the bike. Need to plan better for 6-mile run on RR#2 (i.e. start slow!).
• Core temperature management. Way too hot.

General Notes
• Tested FTP at 263 and set at 260. Questioning that result… Was it just a really good day?
• Recalibrated SRM 3 times during ride.
