Did a group ride yesterday, 18 miles out and 18 back. Strong almost straight on head wind with 30 mph gusts on the return. We talked afterwards if it effected me on the Zoomer or them on bikes more. Consensus was it was tough on everyone. Areas where I could average 18 mph I struggled to maintain 9.5 mph and the bikes were not running away from be. The human torso is a big aerodynamic spoiler.
