I've tried every sort of tactic. The cough, the sniff, the whistle, but nothing seems to work. I have yet to find a good way to alert another rider that I am about to catch and pass them on the trail. (There are a lot of begginer riders in Draper. It's a common place to catch and pass).
Whenever I try to say (in my still small voice), "On your left" or "when you get a chance, I'm coming around" the rider usually experiences a violent, full body shake, followed immediately by a hot flash and almost crashes. It happens all the time. The rider has no clue I am coming up behind them and no matter how much noise I try to make to alert them of my presence, they never hear it. It's not until I actually say something that they hear me.
Is it my voice? Do I sound like a serial killer?
The thing is. I kind of look forward to seeing the reaction. It's funny as hell. It's like watching someone who thinks they are about to die.
