Right now it looks like the only dates in September that are do-able for me are the 7th and 28th. When I looked at the timetables just now, there are so many dates between now and then when one or other of the trains I'd need to take to get to Loughborough are not running or on bus replacement services (e.g. no bikes) - really frustrating.
I might be able to do the 14th, but this date is the last real opportunity for training for the event I'm taking part in the week after (the reason I can't make the 21st), so I'm kind of reluctant to put that down as an option.
