This charity has a number of cycling and walking opportunites (as does the Terence Higgins HIV Trust) for fund raising.
Do check out the related web sites and for Meningitis - phone 0845 1200 664 for details of all their find raising events involving cyclists and walkers.
Do be aware that all funds raised DO SAVE A YOUNG PERSON'S life as this disease has a terrible tendency of attacking babies and people in teens to early twenties.
If word can be spread beyond this forum and to other sites interested in country walking and off road mountain biking in particular - then please do spread the word.
Ta!
