On at the moment. Swisscom have a very nice app with live tracking to follow the teams. Pippa Middleton's team seems to be doing rather well and has overtaken a mate of mine and is catching up with another. The next start is on Friday.
I'm doing the half one (Arolla to Verbier) on Saturday, weather looking to be pants which is a shame but still looking forwards to it! Looks like they had a good race on the first half of the draw.
