So, first item on the gadget radar has to be the soon to be released Garmin Edge 705, the all shiny and new GPS Training gizmo from Garmin.

The spiel says: Trainer. Navigator. Edge 705 pushes you to do your best, then shows you the way back. This GPS-enabled cycle computer knows no limits. Get heart rate, cadence, turn-by-turn directions, power data (from ANT+Sport™-enabled third-party power metres) — the works. Even share your data with other Edge 705 friends after your ride. All wireless with a colour display, this is no ordinary cycle computer.

There is a good hands-on preview here. It seems that the major gripe is the fact that the battery cannot be swapped, so if it dies during a long day on the road you have to be able to recharge it which isn’t much use if you’re out in the wilds.

However, for most training runs (certainly the ones I’ll be doing) that shouldn’t be an issue. Where it might be an issue however, is my Glasgow to John O’Groats trip in August where I wont want to be carrying too much weight. I’ll have to weigh the charger and compare it to a bunch of spare batteries to see if there’s any advantage with one over the other.
