Bigger week and race effort TT

Finally had a week over 10 hours without a big day. Did a half iron race pace 10 mile TT effort today with an avg HR of 144 and maxing out at 148 at the turnaround. Tried to stay zone 2 for the effort. Time was 25:13 for 23.7 miles per hour. Finally the cycling has come back to being easy at such an effort. This bodes well.
