The forecast is clearing... Meet at Browns Waterhole at 05.50 for a roubaix-ish ride to Strathfield train station to catch the 06.37 train to Blackheath. 2 hour trip (and they only go every hour). Then let gravity do most of the work for the 110km trip back to Browns via Springwood, Yarramundi & Castle Hill. That'll make 125km for the day, plus whatever you add for to and from Browns. And home before the rain, feet up to watch the Ashes.
