Race Information
Inside Trail is proud to
showcase this event. Meticulous effort went into the design of the 50k
and 50 mile courses. They are challenging (50 Mile has over 10,000 ft
climb) and beautiful. Every step of the race is run on fresh ground
with no overlapping. Jim Vernon from The Endurables
spent hours and weekends developing this custom, brand new course and
we are super excited to show it off. In fact, we’re so excited, we are
offering a little chunk of prize money!! In the 50 mile race:
Male/Female 1st-$250, 2nd-$150, 3rd-$100, along with special awards for
both distances and age groups.
With La Sportiva as our 2013 partner and Suunto and Hydrapak
as our Marin Ultra Challenge sponsors, we will be giving away two free
La Sportiva shoes and A LOT of Hydrapak gear, including the E-Lite Vest,
Soft Flasks, and water bottles, along with other special raffle awards.
Suunto is providing an Ambit GPS watch to each of the overall winners
(male & female) in both the 50K and 50 Mile.
Starting just steps away from historic Fort
Baker, in the shadow of the Golden Gate Bridge, runners may fill their
lungs with fresh salt air before embarking on a journey through some of
the best trails the Marin Headlands has to offer, including the
beautiful views of Coastal Trail and the inland buffed single track of
the Miwok. You’ll travel along the coast, by Pirate’s Cove, to Muir
Beach. From there, you’ll quietly pass through the Zen center and up
the incredible new Middle Green Gulch hill. Your journey will
ultimately end with amazing vistas of San Francisco and the Golden Gate
Bridge from the SCA and Coastal trails… all the way back to the finish
at Cavallo Point. Aid stations will be packed with all the goodies you
love, plus a generous helping of delicious Clif Products!

Aid Stations
At Inside Trail Racing aid stations it’s like an all you can eat buffet,
but this is a race, so don’t linger too long! Expect to find variety at
our aid stations, including sweet and salty offerings like trail mix,
pretzels, cookies, boiled potatoes with salt for dipping, regular soda,
water (of course!), elecrolyte drink, PB&J finger sandwiches, gummy
bears, salt tablets, you get the idea. There will also be general first
aid items but no anti-inflamatory medicine. We strongly encourage you to
carry at least one 20oz bottle from which to sip while you enjoy your
run.
