For those entering the 50km ride, BNV are offering a "bring a date for free" option:
Freebie friend page:
Entrant and date must attend the GoBike Expo together with the entrant's receipt to comlete registration and collect top.
I would assume those already registered for the 50km ride option can still bring the token date with this offer..
ENTRIES CLOSE MIDDAY 13th October 2011 (TODAY!!!!)
