Trail Hog Half Marathon, 10K & 5K routes

All courses run on the dirt trails of Joseph D Grant park. There are not a lot of steep climbs, but you you will encounter rolling, mostly runnable, hills out there!

All participants can receive a copy of their appropriate course map on race day. Each course will be marked with colored ribbons that are unique to that distance, so that runners know they are on the correct course. Courses are also marked with flour.

From the organizer

Stampeding through the low grasses comes the newest breed of Santa Clara County Park animals, the Brazen Trail Hog! Come join us on Mount Hamilton for a late summer half marathon, 10K and 5K!

Hikers/walkers are welcome!

What’s Included

All runners will receive finisher medals and special t-shirts (available in gender-specific styles and sizes from youth small up to men's 4XL). There will be age-group awards for the top finishers in each category.

Registration/Bib Pick-Up:

Race day registration will open at 7:00 am.

Runners have three options for picking up their bibs and shirts:

1. Mail-out service (for an additional price).
2. We will have pre-race bib pick-up at Road Runner Sports Campbell on Friday, September 20 (10am-4pm). Runners who pick their bib up in person will receive in-store discounts!
3. Pick-up on race morning (not recommended).

In order to avoid race morning stress and avoid having to arrive even earlier, we strongly recommend choosing options 1 or 2. If you are unable to take advantage of those first two options, race morning pick-up will still be available, but you should aim to arrive 70-90 minutes ahead of your race start to account for lines.


The half marathon will start at 8:00 am and the course will have a time limit of 4.5 hours. Runners must reach the 3rd aid station (mile 8.66) by 10:30 am.

Water Stations:

As with all of our races, water stations will be fully stocked with water, sports drink, gels, pretzels, candy, etc.

Water stations will be approximately 2-3 miles apart, as trail access allows.

Runners who may need more water should carry their own water bottle or hydration pack.

I am a very slow runner. Am I going to be out of place?

You won't be out of place at all. Our races are planned for participants of all abilities, including walkers/hikers.

Can I wear headphones?

Yes, but we ask that you keep the volume down at a safe level so that you can hear other runners or instructions from event personnel. We also ask that you remove them, or, at the very least, remove one ear bud when you are coming to aid stations, in a large crowd or on more technical or difficult sections of the course. The important thing is paying attention to everyone's safety and maintaining basic race etiquette with other runners.

Do you offer a group discount? Frequent runner discount? Family discount? Coupon? Special break for running more than one race?

We do not.

Will there be somewhere to leave my warm-up clothes?

Yes, there will be a sweat-check area and these will be checked in and watched over by a volunteer. Bags for storing your sweats will be available if you do not bring your own. Please do not leave valuables in your sweat bags – we cannot be responsible for these items.

Can my dog run with me during the race?

Unfortunately no. As much as we love dogs and running with our own, not everyone is comfortable being around dogs (even if leashed) and for reasons of safety (for those with two legs and four) we ask runners not to bring their dogs along for the race.

Will the race be cancelled if it rains?

No. The race will be held, rain or shine. Courses may be modified to account for weather conditions.
