nerves beginning to jangle

With only a few days remaining before London Triathlon I'm beginning to feel like someone who is sleeping in a new house on their own. Every sound and rustle and creak and beep raises the adrenilin another notch,. Convinced someone is in the house there's holding of breath, cursing being on your own, scrounging around mentally for phones and implements that could do harm etc etc

I feel like I'm in the sporting equivalent of that right now. Every niggle and ache feels like it could explode into pain at any second and therefore give me an excuse or force me out of participating. How I feel about that (i.e. a good or bad thing) varies wildly during the course of the day.

Earlier I was reading about a lady in her 50's who decided to get into triathlons. She's doing the same event as me, and in the same wave. Her last comment was "hey, if you see me, say hello". I'm not sure it's hello I'll be saying versus why in God's name and are you mad and all the while silently offering a prayer that I'm not still putting myself through this when I'm 50.

That being said, I think what's she's doing for herself is fantastic, really. If somewhat worrying.

Anyway, training wise, this morning I just did a 15 minute run. The bad news is I was pretty knackered afterwards. The good news is there's nothing I can do about it so no point in worrying.
