Yep I broke out after I started biking. I did two things: 1. I think my skin needed to adjust to the sweat/ contact spots (okay not helpful but a little bit of patience) and 2. I started using some more heavy duty face washes. My favorites are for pre ride Oxy daily face wash maximum with Benzoyl Peroxide and post ride Oxy daily cleansing pads with salicyclic acid. I like the second one because it gets rid of the pollution than gets attached to my face ( you would be amazed) and it is really easy to clean my hair line, a neglected spot with normal facewashes. Oh and you can clean your neck without a mess too! Goodluck with the breakout I sort of think everyone goes through it.
