Easiest way is to suck the tail of those fast guys. 18 mph will feel like 14 by yourself.
A month ago, I was tootling down quiet streets when the U of A Tri team happened along. 2 guys leading and 2 girls behind. So I couldn't pass this chance up and I cranked up my roadster 1973 CCM 3 spd to 18/ 19 mph and kept up for a km until they went the wrong way, darn. The girls were looking back at me. LOL
