I did my first Audax last year, Beacon Road Club's Cotswold Outing, very good too. I printed the route cards in a sequence of A5 sheets, laminated. This was fine, except the only way I could read them with my aging eyesight was to hold them out at arm's length which may possibly have made me look a bit of a prat. I now ride with bi-focal wrap around safety specs, which means I can now mount the route card on a handlebar mounted clipboard and still see both the directions and the mileage counter on the cycle computer; two helpful things on an Audax. This year I'm going to remember to take a pen too so I can note the control data. I clocked up an extra 4 miles or so getting lost, but every mile helps with the mycycling mileage log.
