Good finish Iggs! The conditions were tough for many, so just having the commitment to go to the last race in swampfest conditions, staying somewhat together, and finishing is an accomplishment.
I found when I first started racing I saw improvements so easily, but once I got into Cat 1, noticing improvements was more subtle. As I improved so did everyone else and some faster than me. At that level there is much more commitment in training. My biggest brake through was not noticed as just getting faster, but getting more efficient.
Either way, great to see you doing well in the big pool. Hope you come back for more next year!
