As a two country event we have two of most things, including registration sites. For logistical reasons we prefer Canada based runners to register on the Canadian site and USA based runners to register on the US site. Runners from other countries may register on either site.
To register on the Canada site click here: Canada Registration
To register on the USA site click here: USA Registration
If you are from neither Canada nor the USA you may register on either site.
NOTE: Registration for the cross-border races closes midnight 31 May to allow for border security clearances. 10K runners may continue to register through Midnight 22 June.
