It is important to stay moving and not drink too much wine while running! Our volunteers will be there at the 1 mile loop start/ finish to help you if needed.

Aid Stations: DO. NOT. technically EXIST. You are required to be self sufficient or provide your own crew. There will be some race director drive by car aid and assistance with fuel & water refills, but these will NOT be often and you will need crewing or self stashing. If you choose to leave the course, to sleep in a hotel or at home for a part of the course, you will have to check in with race director and confirm that you are leaving from a specific location to which you must return to the exact spot to continue your island pilgrimage.

Time Rules: 100 miler has a firm 48 hour cut off. If you reach the finish at 48:01, we will be very happy for you but you will not be an official finisher. 260 milers must complete a minimal of 65 miles per 24 hour day. Do not underestimate this. We recommend you have completed a 100 mile run within the last 24 months, or have experience with multiday stage races. Your final cut off for the 260 miles is exactly 96 hours from your start time.

Gear: Running between 6 pm and 7 am requires you to have lights & reflective apparel.

Pacers: For the longer distances runners may have  a pacer after mile 50. Pacers are optional and sometimes quite enjoyable, but not necessary. 50k people must run solo or within a safe distance of another racer.

Relays: You May break up your distance in any length of segments you choose, but you must always have a runner running (obviously). With your crew vehicle it must completely pull off the road and not block other runners or crew vehicles. Please be courteous to all parties involved.
