COVID-19 Related Race Update

A new twist on an old favorite! This year's Folsom Lake Trail Run will look a bit different than in years past. We will have a new start/finish area, and we'll only be offering one distance with wave starts. Keep checking this page for more information as we can make it available.

In the event this race needs to be cancelled due to COVID-19 related lockdowns, there will be no refunds. Instead, we will be offering a credit to any future ITR race. This credit will be good for 2 years after the date of the cancelled event.

Race Information

Folsom Lake is a popular destination for campers and boaters, yet also offers lakeside trails that meander around much of the 75 miles of lake shore.

Our annual Folsom Lake Trail Run will look and feel very different in 2021. Due to COVID-19 restrictions we are only hosting a Half Marathon, that traverses the beautiful lake side trails between Brown's Ravine and New York Creek.

Without the support of enthusiastic and caring volunteers producing our races would not be possible. Volunteers of all ages and abilities help with setup, check-in, aid stations, course marshaling, timing, and post-race food.

Volunteering is a fun, novel way to experience races, play in the outdoors, and spend time with friendly people. All volunteers receive a free race T-shirt, free food, and the ability to earn credit toward a future Inside Trail Racing event, commensurate to the amount of time worked. Five hours of assisting an event results in a free race credit or Inside Trail merchandise.

To volunteer for this year’s event, please submit our online volunteer form.

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.


All registered runners will receive a District Perfect-Tri tri-blend fabric shirt. This tee is made with top-of-the-line sportswear technology to heighten performance during your toughest workouts. With sun defense, moisture-wicking technology, quick stain release, and comfortable fit, this tri-blend performance crew serves the needs of every athlete.

The Fine Print

Entry fees to our trail runs are non-refundable, and we do not offer transfers or deferrals to future races. Only registered runners can participate, and you may not exchange your entry with another individual. However, with advanced notice, we are happy to credit part of your entry fee to a future 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. All race costs are paid for well in advance of race day, so there is no financial gain to be made if a person does not show up on race day. 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.
