I use a Petzl Tikka XP2. Its very light, but very bright. I usually use it in 'spotlight' mode if the trail is totally dark and uneven, but the diffuser mode is also good if you just need a general light and can be fairly sure of your footing (ie dark paths / roads / wide trails)
+1 shuffle. I clip it to the band on my shorts and run the wire down my back under my top. Keeps the cable neat, and I can skip tracks etc easily. You dont need a screen whilst running -and the shuffle will say the name of playlists through the headphones making it easy to chose what to listen to.
I find it varies loads between makes and time of the year. I do think though that the Asics Cumulus I had lasted the least number of miles - dont know if the Nimbus are the same. They felt great when I first wore them, but only lasted about 250 miles until they felt like they were running on cardboard. I dont want super bouncy shoes, but at least a little comfort. I'm on Brooks Ravenna now, and the pair I have are up to about the same and still feel fine.
Thanks Anna. Sorry - but one final question. Are you expecting Larking Gowen to extend the initial agreement to sponsor the event past 2012 ? I know its early days.....but it has proven to be a very successful event, well supported and very popular. It would be a huge shame if it did not continue into the future.
