Towel for bike. Check.
Large Fan. Check
Motivated and Ready. Hmm (a little scared to be honest)
Here's how it went
10 mins warm up starting from 53/21
Quick sip of water
20 mins @ 25 mile TT pace/intensity/power in 53/17
8 minutes recvovery break - bloody tough, siped a coke and then fruit tea

15 mins @ close 25 mile TT pace/intensity/power
5 min break (more drinking and sent text message to my boss)
20 mins @ close to 25 mile TT pace/intensity/power
Phew! five mins warm down
How did yours go?
