How fast am I really going?

I've been training for my first open-water swim in a lap pool. The event is only one mile and I've been swimming it in about 29 minutes. Is that fast or not? I'm not entirely sure. Also, how does lap pool swimming translate to open water in terms of time. I know I need to take into consideration the sighting, temperature and not having walls to stop at/push off, but should I expect to swim it in 29 minutes? Or is that unrealistic?:cane: I have only done the one OW swim round a very calm lake about 80F, more like a large pond really. It was 1500m and I finished in a little over 23 mins, which was about the same as I had swum a 1650yds in the pool in training earlier that week. I was a bit put off by the skinny minnies and muscular guys to begin with, but followed the lead kayak and was first out of the water! Sound's like you'll do fine - enjoy it - its a new and different experience:) Which reminds me, I need to enter this year's race.
