Cleave - Yes, it's a weekday training series, and the course is wide and flat: cones marking the turns, in a stadium parking lot. It was very windy, so maybe that was partly why people lined up the way they did.
I did exactly what you just pointed out: charged to the lead, cooked myself (MHR for 4 minutes), and was unable to grab a wheel when the first few riders went past. They weren't even moving that fast, but made their move on the uphill/upwind side as I was slowing from cooking myself.
I'll try not to yell "Cleave!!!" at you in a tight congested corner!
