Thanks BCB. Good point about the distance - I had read that before but forgot all about it. I'm feeling great about my time as I certainly didn't start the race thinking I'd beat an hour; I just wanted to finish.
I love my Garmin. It's perfect for running outside, though I'm having a few probs getting accurate readings on the treadmill with the footpod. It seems the calibration isn't right as I've run for 20 minutes and the Garmin stated I'd only run 0.25 miles and I'm not that slow! As for the advanced training stuff, I'm still getting used to that, but I shall definitely have to utilise it for future training. Also, on the 410, people complain about the bezel. It just requires a bit of patience. I've hardly had any issues at all.
Brilliant! Thanks for that - I'll definitely try it. I've got another 10k in January so now I've got my first race (and first PB) sorted I've got something to aim for next time.
