The trail surface is finely crushed limestone over a dirt bed and is described as smooth with minimal technical sections. The famous tunnel is crossed twice by 50 km and 50 mile runners and four times by 100 mile runners. USATF and World Athletics course certifications are in place. Time limits for the 100 mile, 100 km, and 50 mile are 30 hours; 100 mile runners must begin their second 50 miles in under 15 hours.

Aid stations provide standard runner fare including hydration drink, fruit, hot foods later in the day, and limited cups; athletes are encouraged to carry their own containers. Porta johns are present at every aid station and some stations offer running water. Drop bags have recommended size guidelines and will be transported to aid locations. Pacers are permitted under specified rules and USADA drug testing protocols apply to the USATF championship division.
