For those not familiar with it, the White Rock Creek/ Lake trail is just almost flat- a couple of rises that don't slow you down much- so I can do it faster than the charity rides, which tend to have actual Hills. So I'll pass some people, and have other guys go zipping past me on occasion, too.
And on the charity rides, I'll be trying the ones with the least hills, not just random ones.
Everyone knows there aren't any hills in Texas
