I just finished a 15.891km cycling that lasted about 0hh:33mm:9ss !
Tried out our first race in Watopia using Zwift this morning. Myself, 
Something like 190 people racing in the heat.
Actually pretty surprised by how fun it was. And how hard it was too. Definitely need to come out of the gates a little bit hotter next time -- people get a FAST start in these races. Going to try to get a few training rides in throughout each week, and get a race in on Sunday mornings. Motivation to get in shape and drop a couple pounds.
