A friend got a corporate invite to ride Dusi2c, and asked me to help kit him out with everything he needs to get riding, get fit and get ready for the event. I could guide him on most bits, but when it comes to GPS units, I'm as in the dark as he is (I use Strava on my phone, turn it on, forget about it until I finish my ride, and upload my ride). There is an oldish thread here on le Hub, but it's not very definitive. I'm partial to the Garmin Fenix 3 HR, the downside being that it's on your wrist, and not on the bars in front of you, not great if having to follow a route, but how much route following is really done in these races, unless you're riding the Munga?
