Time Limits and Cut-Off Times:
The time limit is 33 hours for 100 mile runners. We're hoping the shorter distances fit under that limit. :) The intermediate cutoff time for the 100 mile run is to reach 50 miles in 16 hours or 11 pm. You should arrive at the 75 mile mark within 24 hours or 7 am. We don’t want to pull anyone from the race. If you arrive after a cutoff, we’ll work with you to calculate a best case finish time and help you make a decision as to whether to push on. While we want everyone to finish the event however, it is not always possible. Aid station captains have race director authority to stop any runner for safety reasons or if they are projected to not make the 33 hour time limit.
Placement Awards are given to the 1st, 2nd and 3rd place overall female and male finishers in each distance, as well as age group winners. Custom coasters will be given to the 50 and 75 Mile finishers, and buckles will be given to 100 Mile finishers. There are two buckles: sub-24 hour finishers’ buckles and over 24 hour finishers’ buckles. Marathon runners will receive a Headlands logo and dated finishers medallion.
Aid Stations/Drop Bags
We will provide a variety of fresh fruit, salty snacks, salted potatoes, PB&J sandwiches, salt tabs, sugary snacks, Clif Shot bloks, electrolytes sports drink, Coke, ginger ale and water.
Rodeo Beach and Tenessee Valley Aid Stations will have soup and “real” foods during the night and second morning.
The 50, 75 and 100 mile runners may bring drop bags with personal needs which we will transport to aid stations. The drop bags will be returned to Rodeo Beach at 3 p.m. on Sunday, September 10.
In addition, it is highly recommended that runners carry at least 20 oz. of water between aid stations.
