Did it yesterday, 10h 25mins moving time. Got lost a few times, could certainly improve on that but no desire at the moment!

Set off from Winchester at 6:30 and rode into Eastbourne with the South Downs MTB boys.
Doing it on a CX bike was pretty painful. Was interesting comparing ourselves to some MTB groups we saw, at times we would pull away, up the really steep stuff we didn’t have the gearing where the MTB boys could spin. I came off twice, once when it rained in the morning and I lost it on some chalk and the second time just a concentration lapse and went over the bars into some nettles. You can’t stop paying attention for a second on a CX bike on the SDW!
A memorable and mainly enjoyable day. Sore today though!
