Chris & Dawn, I have emailed them to see if more tickets will be available to buy, the 1st 4.5 miles of the course will be open for spectators if not I guess, I i'll let you know what they say,
The stadium holds more than 10,000 people so i see no reason why they wont look for a way to cash in on the rest.
i hope not everyone buys 2 or 3 more.... running into a stadium with 20,000 spectators...eek, no pressure
