Running with Boys

At tri club lately, there havent been any girls for me to really run with. Which is fine, but that means I end up running with boys.
And hauling ass to keep up. It isnt really that they are boys, just that I seem to be the only girl with them alot of the time.
My choice is either run with them, or end up in no mans land, running alone, as the next group is quite a bit slower.

So for now, I haul ass. I figure it is ok to do once a week. Tonight the run felt pretty up tempo for me. It also included a large hill. Now I am tired.
