The event in the OP does as it is a fund raiser for The Poppy Appeal (£33,803 last year), and is on a set date. The plan last year was to also set a world record by having over 153 complete the ride, sadly the colonials got wind and upped the anti to just over 400. 187 did finish the ride which is a 'rest of the world' record. The beauty of doing this event is that the organisation is done for you, as is a route plan that will cover 1000 miles, your speedo reading is not proof enough Why Last year I rode with two Pan Europeans they recorded about 1150 miles, my Dragstar recorded 1008 miles the actual certified mileage for our route 1042 miles, that's why. You can do a SS1000 anywhere in the world, to be certified you need a paper trail (usually petrol receipts & log & start/end mileages with independent witnesses) Take a look on the IBA website http://www.ironbuttuk.org/index.html Pete West may be the best one to contact, he rides a bit, did a BunBurner GOLD (1,500 miles in 24 hours) last year. Hope that covers a few questions.
