I was thinking it's about time the challenge that's been on hiatus longest ought to return... so I thought let's organise an event for it.
Start point: Epping
Finish point: Heathrow Terminal 5
Date: Saturday 9th November 2019
Time: tbc but likely first teams depart about 11 - I believe there's a handy Roding Valley parkrun nearby for the parkrun inclined? Teams depart every 20 minutes to coincide with loop trains.
Post Challenge Meet: Either The Green Man (Hatton X) or something else as otherwise advised...
