The whole stage was 13.5 miles. The stage before ours the woman ran solo (with a support vehicle that's doing the whole relay) at a staggering pace - a couple of degrees cooler, but way hillier. At least one or two of the overnight stages last night went through severe thunderstorms - don't know how severe it was out on the course, but we had massive amounts of lightning here. And the baton kept moving. It's got a GPS tracker so you can follow it on the website (and join in or cheer if anyone is nearby). And such a feeling of community among the runners. What an incredible event. I wish I'd done more of it - if I'd known about it earlier I'd probably have signed up to do the whole stage - but I'm really glad I got a chance to participate.
