About the Race
This event is run entirely inside the Marshall Gold Discovery State Historic Park, set in the beautiful foothills of Coloma along the south fork of the American River. This is the site at which gold was discovered in 1848, igniting the gold rush and leading to California’s quick rise to statehood.All of the courses are a mix of very appealing single track dirt trails and a few paved areas. There are some moderately technical ascents and descents with a lot of switchbacks. There are also some sections of rolling hills and other places where the course is completely flat. With the addition of scenic views and a variety of wildlife, there is plenty to make this run very enjoyable and interesting.The race is held rain or shine. Be aware that it can be very cold in Coloma in the morning. No strollers are allowed in the race.The time limit for this event is 4.5 hours.

Inaugural Year — Where History & Grit Collide April 30 – May 2, 2027 | Georgetown, CaliforniaWelcome to the inaugural Harvest & Howitzer Backyard Ultra — a last-runner-standing race on a private 100-acre Christmas tree and apple farm in the Sierra foothills.The premise is simple: one 4.167-mile loop, every hour, on the hour, until only one runner remains.Built by a team rooted in ultrarunning, Western States, Tevis, trail work, volunteering, and community, this race was created to feel like the sport we fell in love with: hard, honest, personal, and full of people who show up for each other.No traditional finish line. No quick medal-and-go experience. Just grit, hospitality, history, and the question every runner faces each hour:Do you have one more loop in you?This is the backyard ultra you came for.This is a gathering of the tribe. The Heartbeat: Community, Crew & Campfire This is a weekend campout, not a quick race. A private farm. Campfires, crews, families, and the space between
loops—where the race really happens.Come prepared to stay. Bring your people.No corporate noise. No overproduction. Just land, loop, and community.Includes a kids' race. Proceeds support local nonprofits. The Howitzer: Know When to Lay It Down In 1843, Frémont hauled a 1,200-pound cannon across the West—through brutal terrain, rarely used, never abandoned.Until survival forced it.He left it in the mountains.Hauling the CannonEvery runner carries their own howitzer—power, pride, stubborn will.You push for hours, sometimes days. But this race is strategy, not force.The best know the edge.And when it's over, respect goes to the runner who pushed to the limit—and knew when to lay the howitzer down.

Race Information The No Hands Heavy Half became an instant classic in 2021. We upped the ante and added a 35K and 50K to the mix.Participants of this race will run along the historic Western States trail, out to “No Hands Bridge”, then tackle one of the toughest climbs in the area: the dreaded K2 training hill. Both the 8k and Heavy Half courses include killer single-track trails along the banks and canyons of the American River; the Half Marathon will cross “No Hands Bridge”, up K2 then towards Cool, CA. Not to be outdone by Training Hill, everyone will climb the punishing Overlook Hill to the finish line, where you’ll revel in the 50 meters of perfectly flat path. 50K runners extend the adventure by crossing over highway 49 to traverse the Wendell T. Robie trail and continuing to explore the Auburn State Recreation Area. The Half may be heavy, but the 50K is down right Furious. The course is varied and far from monotonous, allowing runners to push past discomfort and focus on what’s
enjoyable.Location: American River Overlook Park (Start/Finish Area) Events: 8K, Heavy Half Marathon, 35K, and 50KStart Times: ● 50K & 35K – 7:30 AM ● Heavy Half – 8:00 AM ● 8K – 8:30 AM Check-In & Bib Pickup: Early Pickup Fri., January 8 3:00 PM – 7:00 PM Fleet Feet Roseville 1850 Douglas Blvd Ste #418, Roseville, CA 95661 Race Morning Sat., January 10 6:45 AM – 8:30 AM American River Overlook Park (Start/Finish Area) Time Limit: There is an 8.5 hour limit for the 50K.Parking: Parking is free and available within the American River Overlook park, and adjacent streets.

Course Information Detailed Course Map | Aid Station Distances and Cutoffs | Elevation Profiles Aid Station Supplies Inside Trail Racing aid stations are replete with an optimal variety of glycogen-replenishing, electrolyte-replacing products. The following
is a list of some of the foods and beverages each aid station may provide: Gu Energy gels, chews, and Stroopwafels, trail mix, pretzels, potato chips, Oreo cookies, Coke, Ginger Ale, water, Skratch Labs Sports Hydration Mix, PB&J sandwiches, M&M’s, salt tablets, bananas, watermelon, and tangerines. Aid stations are also equipped with general first aid items, including Salt-Stick tablets, but no anti-inflammatory medicine.Skratch Labs is 80 calories per serving with minimal sugar (4g per 100 ml) and a ratio of sugar (glucose + fructose) that is optimized for faster absorption, an electrolyte profile that actually matches what is lost in sweat (800 mg sodium, 80 mg potassium, 100 mg calcium, and 80 mg of magnesium per liter)As distances between aid station vary, we strongly encourage all runners to carry at least one 20oz bottle during their run. Cupless Event This a cupless event, meaning aid stations will not have paper cups available for runner use. Each runner will be responsible for
carrying their own water bottle or reusable cup. Reusable cups are made of silicone, are collapsible, and easy to carry with you while you run. Going cupless will keep hundreds, or thousands, of paper cups from being thrown away or left littering the trails. Read more about our cupless events here. Reusable cups by HydraPak will be available for purchase at each event for $5. Volunteer Without the support of enthusiastic and caring volunteers producing our races would not be possible.

Inside Trail Racing event. A credit worth 50% of your original race fee will be issued if the cancellation is received at least 3 weeks prior to the race. There will be no credits or refunds provided if a cancellation is made within 3 weeks of the race. Credits will be available for 1 full year from its issue date. Only registered runners can participate, and you cannot exchange your entry with another runner.Hosting a trail running event is an expensive and risky endeavor.

We want all of our registered runners to show up, run, and have fun. While we understand that injuries, conflicts, emergencies, deaths, and other unfortunate events happen and may impact your plans for participation, we must adhere to our cancellation policies.We do not cancel races due to rain or heat. Due to trail work, closures, or for myriad other reasons, permitting agencies may
require changes to the publicized courses at any time prior to an event. This is out of our control, and we therefore will not offer refunds or credits in such a situation. If a race location is changed, but still hosted on the same day, we will automatically transfer the registration over to the new venue, or entrants may choose to run the race remotely and we will mail awards. If a race is postponed all entrants will be transferred to the new date.If the situation does arise where ITR must outright cancel an event, for any reason, there will be no refunds. This could include earthquakes, floods, extreme weather, unsafe air quality, pandemics, or any other "Act of God". There will be no refunds, but future race credit or deferrals may be available, dependent on the circumstances and how close to the race date the event was cancelled. We will communicate with all registered runners as soon as possible regarding the cancellation and any pertinent information. Event's current local time: 1:59

Iron X: An Extreme Ironing Race Iron X is an extreme ironing race. Ironists (participants) will run a portion of the historic Western States Trail and iron in some of the most iconic Auburn, CA locations while running a half-marathon.What is extreme ironing? If you're not familiar with the sport, please read this first.Disclaimer: This is a fatass - a glorified group run. There will be no course markings, no medical, no medals, no trekking poles, and no pacers allowed.Links: Iron X LinkTree Iron Locations 1. The Foundation Iron (middle of the old foundation at Robie Point - this is the main structure's foundation, just past the 3-sided "garage foundation.")2. The River Iron (at least knee deep in the river, just S of No Hands Bridge)3. The Foresthill Bridge Iron (top of Kickass, E side of bridge, S side of Foresthill Rd)4. The Dead Car Iron (on top of vehicle remains)5. The Statue & Train Car Iron (next ot the statue's foundation block, E side of Lincoln Ave between Elm & Harrison, downtown
Auburn)6. The Clock Tower Iron (in front of/next to it, Lincoln Way at High St, downtown Auburn)7. The Courthouse Iron (in the parking lot in front of the historic courthouse building)8. The Claude Chana Statue Iron (at the corner of Park St & Washington St, Old Town Auburn) Rules Ironists must wear a button-up (or snap-up) shirt throughout the race, removing it, ironing it, and then putting it back on at each of the above locations (you may wear another shirt underneath).Spectators are allowed at all ironing locations except for The Dead Car Iron.Proof of completion: Post-event, ironists must submit their activity link for verification. (Make sure your activity's privacy is set to public.)Ironists must also take a photo or video of themselves ironing their shirt at each location and submit these, post-event. (We suggest uploading them to your Strava activity. If you're not on Strava, you can submit via email - details on this process will be emailed, post-event.) Each photo or video must
be geo-tagged, so make sure location tagging is enabled in your camera settings. (This enables their visibility on Strava activity maps.) The location, ironist, iron, and board must all be clearly visible and apparent in each video/photo. Having another ironist or spectator take said photo/video is also acceptable, provided they are on location at the same time. "Spectator crew" are allowed for this purpose, but this is all they're allowed to do. Providing aid or assisting in any other way is not allowed, with the following exceptions...New in 2027: We will allow aid at the Foresthill Bridge Iron and the Statue & Train Car Iron. You may bring a drop bag to the Start for this purpose. (This is a moving drop bag; it will go to both locations.) You may also have crew at either or both of these two locations.Penalty: Failure to complete an iron in the location specified and provide the required video or photo evidence will result in a penalty of 10 minutes (added to your finish time) per
location.Gear & Supplies: Each ironist must provide their own ironing board, iron, fuel, and water, and carry them with them throughout the event. No muling allowed.Preparation: There are a few different methods of carrying your ironing board to consider.1. Strap your board directly to your pack. Finding the right pack for this purpose is tricky. Snowboard-mountaineering packs may work, but snowboards are generally a bit narrower than ironing boards. Separate straps could be used to secure the board.2. Add 2 shoulder straps to your board and wear it on your back.3.
