Audax rides

I've actually signed up for The Dean (and a couple of others in increasing length further down the line) - I'm supposed to be staying in the Travelodge the night before so no worries there, however, I appear to be cutting it a bit fine with making to the last train at 23:15 on the Saturday following the ride, I'll need to be quite vigilant with time/avg speed to get it all done.

Are you doing The Dean? and is anyone else from on this forum?

I'm seriously considering it as I'm local although it may be a bit much as a first given I've only ever done centuries before.

Given I've got rack fitments I'm tempted to go rack with rackpack and maptrap although I've also got a garmin 800.
