From the
Start List section of the TD site:
Tour Divide accepts letters of intent (LOI) annually, from Winter Solstice (12/21) until Grand Depart (2nd Friday in June). Prospective challengers are encouraged to declare, but may also simply show up in Banff on June 10th. To be published on the provisional start list, send us an LOI via the
contact form.
Note: The info on the site says "show up in Banff on June 10th but it really should read the second Friday in June."
