Fiesta TTT and did 2x20K. We knocked 1 minute off our 40K best total and each 20K was within 5 seconds of each and 23 mph. Fiesta had typical crosswind so not really fast conditions.
Riding outside was like smoking a couple of packs of cigarettes due to the air quality. Hopefully, it will improve. Improving 1 minute for 40K is the equivalent of shaving ones legs. So it goes.
