As I sit watching Olympic short track speed skating, it reminds me of something. That something is what happens any time there’s a challenge for position in a pack of bikes. I’m always the first to back off. Now, I know that’s not much of an issue in non-drafting triathlons, and that’s probably why I haven’t put a whole lot of energy into fixing that problem. My general impression was that it’s just my nature to get pushed more easily.
Gee. When I write that out loud, that looks pretty ridiculous. Suddenly I remembered that I’m not like that swimming nor running. Nope. Even if I’m the smaller party in an interchange, you’d better believe the space infringer will find themselves in an uncomfortable interchange with a pointy elbow while I don’t miss a stride or stroke. Maybe it’s time I start using my elbows on the bike. Metaphorically. Back off, dude. Yeah, I mean you. 
I know what you mean. It seems that as soon as I get going in a group ride I always identify the one person there that I know is going to make me nervous. There’s always one.
