I've never used one of the vest things, but I'd recommend a watch (I use a Garmin 235). You want something you can look at while you're training - seeing that you're x% off your target really motivates you to try harder!Thanks. What about those GPS things you could put into a vest? Where can I get one of them?
Yup, if you get the Forerunner 235 you get constant heart rate monitoring which adds to the fitness metrics. There's also a half decent refs timer app in the App Store which I use (vibrates to remind you time is off etc)
But of course... Duh :Zip:Referee Watch
