We are sold out!
One of the nicest settings for triathlon and duathlon. Very compact triathlon site that creates a fun, family friendly atmosphere! Very quick drive from Toronto on race morning! Race in the morning and check out Wine Country after your race! For those ladies who are also looking to compete in the IRON GIRL race; this is the same race site. Come get yourself ready for big race by first trying out the Try-A-Tri, which uses portions of the same routes you will be using in the IRONGIRL event!

The second visit to Guelph Lake Conservation Area is the perfect way to cap off your season on the Labour Day long weekend!
