Refund Policy
If you are unable to attend a registered event, a refund may apply toward another 2025 race registration or donation for YBONC Programs. Contact us by email (no IM or calls) and we will reply with a registration coupon code to apply. We understand life happens and we ask you to please understand we are a small not for profit run 100% by volunteers. Our expenditures are incurred when participants register and vendors (registration, state parks, USFS, medical, etc) do not offer us refunds so in order to stay afloat, the best we can do is offer credit to another race. Thank you for understanding.

What is CA Dirt MTB Series?
The Series is a YBONC Foundation fundraiser to support Nevada County school bike clubs, approximately 220 youth county wide.
ALL racers who finish in the top-15 in their category and class at any of the CA Dirt MTB Series event qualify for USA Cycling’s MTB National Championships. Only riders from California who hold a USA Cycling annual license are eligible for the State Championship.
Can I race if I’m not from California?
Yes, just as a registered racer in CA Dirt MTB Series, we still are awarding top 3 podium spots with our locally made CA Dirt MTB Series medals.
USACycling’s State Championship requirements are …
Must be a California resident
Must complete minimum of 2 races
Must hold a current annual USAC license BEFORE racing in Race 5
What is a USA Cycling CA State Championship Series?
A USA Cycling MTB State Championship Series includes two or more events in which riders accumulate points in discipline/class/category/age toward an overall total for the series. The highest ranking rider of each discipline/class/category determines the USA Cycling State Championship winner.
How do I qualify for Nationals?
The top 15 riders in each category overall at end of series qualify for MTB Nationals and must hold an annual racing license to register for nationals. If it is an “open” category (ex: Junior 10-14, Men 60+), they qualify to race at nationals in whatever category is listed on their license as of December 31 of the current year.
Will I qualify for nationals with a one-day license?
You will qualify for Cat 2 or Cat 3, but you must purchase an annual racing license before starting Race 5 of series.
Do I need to buy a USA Cycling license to race Cat 1?
Yes. To race at an individual race in the CA Dirt MTB Series, you may race Cat 1 on a one-day license ($25) purchased on-line at USAC.
Registration says it’s open until 12Midnight Pacific Daylight Time, prior Wed (or prior Thurs) of race day, and it says it’s closed? What gives?
Technically, it is open until the posted time and day however, the registration service we use may be doing maintenance or have server issues. We understand last minute decisions very well but we cannot promise the internet is always functional at the moment you wish to use it!
Why don’t you have a category for Cat x or Age group x, etc.?
Our categories are based on past attendance. Although they do occasionally change based on need, they are carefully analyzed to provide a fair distribution of distance and ability while keeping costs and time involvement reasonable for the promoter. Very few people want to race in a category by themselves. We do retain the right to combine categories with less than 5 to match national practices, but rarely do so. USA Cycling official on site will make the decision.
When are results/series points/USAC rankings going to be posted?
In almost all cases, results will be posted to the USA Cycling’s race result website by midnight the day of the event. USACycling official will be present to verify race day results before podium. Every effort will be made to keep series point updated and results sent to USAC in a timely manner.
I bought USAC One Day license for Race 1, 2, etc. and decided to purchase a USAC annual license. Will I be refunded for the USAC One Day licenses?
No refund. This is a USAC policy - NOT YBONC’s. Your one day license purchase will be applied toward an annual license purchase.
I missed the awards ceremony, can you mail me my medal, etc.?
If you know you are going to miss podium on any RACE Day, complete an envelope at check-in with your name, address, race no., plate no., registered category, and $3 for shipping. Medals will be not be mailed if you do not complete an envelope. Medal(s) will be mailed after Race 5 – 07/07/19.
Can we do more/less laps for the (insert category here)?
In many cases, yes. If the entire group wants a change from what was advertised, this can be requested and changed during the riders meeting. The promoter reserves the right to make a change or deny a request based on course and weather conditions and/or rider safety. Decision to be made after discussion with USA Cycling official on site. Decision announced at the racer pre-race meeting line up by category 10-15 minutes prior start times.
What are the requirements to upgrade categories for CA Dirt MTB Series?
Per USA Cycling, riders can “self select” to upgrade category with approval by USAC official or event director on site. Lower category points are not included in the category upgrade. Proof of current license required at race.
To upgrade to Cat 1, riders should have at a minimum 2 top 5 finishes in events with the minimum category size.
Cat 3 or Cat 2 riders must upgrade after 5 top 5 finishes in minimum category sizes. Refer to the 2019 rulebook for minimum class sizes for upgrade purposes. Upgrade and downgrade requests can be done with the USAC Official at the race. (Note: This may not apply at other races outside of the California Dirt (XC) Series)
Is there a course map for races?
Yes there is if race is on public trails. If course map is not posted, there usually is an agreement with land managers to reduce rider use conflicts. In those cases, maps/routes will be posted a few days to a week before the event, and on Race Day near check-in booth. Please respect our land manager of private lands by only practicing only on designated date/time.
If you have a child racing Jr. 6 – 14 y.o. racing…We are not responsible for taking care of your children on course. We support participation - we do not provide childcare.
Our goal is a safe race for all participants. The goal of a first time junior racing should be to complete his or her race, not necessarily make podium by taking unskilled risks. A junior racer must be able to complete race course 1 hour or less for safety of all competitors. Our sweep has authority to inform any junior racer the 1 hour limit, and racer is designated “DNF-Did Not Finish” on race results. If this is your child’s first race and he/she is not confident racing yet, we request you bike along with your child for support so our sweep may continue supporting the juniors field on the course. We are requesting parents not to race and to support his or her child who is racing. We cannot reach you if you are racing on the course, if your child needs you for support or a shuttle. We are not responsible for your child if he/she bonks and decides to stop during the race.
