I just spoke to someone there and "they are sending them out as we speak and are on M and working through them alphabetically" apparently. She was more than happy to confirm reciept of my proof of qualification using my postcode and said that they'd be out at the end of this week / early next week.
To satisfy my curiosity, I went for a 'test run' yesterday. Yes there is a hill, but there is only one and it is definately the case that 'what goes up must come down' as the downhill section on the other side is a lot of fun. Also I'd never been to Henley before -it's beautiful! I only ran the second half of the route so am looking forward to the views along the river too.
