Wharf to Barf 2020 is Thursday, July 23rd through Sunday, July 26th. The event is currently unaffected by the Covid-19 health crisis, but will be changed if need be.
If you are interested in officially running the Wharf to Wharf race, details can be found here.
Bibs go on sale starting March 25th and sell out incredibly fast, so get yourself on their mailing list as quickly as possible if you want to be all above-the-board on everything. Having a Wharf-to-Wharf bib does not effect Wharf to Barf, but it is an excellent time.
