From the Madcross e-list:
"
Don't forget that tomorrow (Thursday) at 4pm pre-registration for the USGP Planet Bike Cup closes. If you haven't registered do so at http://www.bikereg.com/events/Register.asp?EventID=9185
Racers in the non-elite races can register day-of for an extra $10 and must do so at least one hour before the race start. Elite men and women must pre-register.
Thanks,
PS - The course is looking awesome this year and we're back on the hill we all love but it is going to feel a bit different than the past with some new twists/turns. You can pre-ride on Friday afternoon from 2-4pm."
