Venue and logistics

Wetsuit use is optional and expected to be suitable as water temperatures are likely to be warm enough. A secure transition area will be in place; race and bike numbers must match racking positions, bikes must be numbered, and helmets must be visible before entry. Bib and bike numbers are required to collect equipment after racing. Visit the organization's website for the most recent information.
