The race starts at 12, so you'll need to be there for 11:30.
you can do it in your slalom boat if you want, but I've got a couple of Whoppers and lightenings (wwr or sprint boats) Give me a call if you want one (that goes for any one else too...).
The rowing club's address is: Durham Amateur Rowing Club, City Boathouse, Green Lane, Durham. DH1 3JU, so you can google it and get directions.
