Although I missed this at the time, a bunch of Caterham and Lotus Sevens drove from Land's End to John O'Groats to raise £5000 for Leukaemia Research.  The convoy of fifteen cars started on Saturday 18th August from Land's End, reaching John O'Groats on the Monday.  In the end, the event raised over £7500 and I'm sure further donations would be welcomed.  See the LEJoG website for details.
