Want to take the skills you already have to the next level? Gravity Academy is an intermediate to advanced camp led by professional coaches that have the knowledge to elevate your riding to new heights. The camp will focus on jumps, drops, cornering, descending, and other crucial skills for freeriding. We will also do some trail work to keep the tails running great! Our coaches understand that jumps can be intimidating; don’t fret, we strive to create an inclusive, supportive, and safe environment so that everyone feels welcome and ready to learn.

This is an intermediate to advanced level camp for students interested in gravity style riding; freeride, slopestyle, dual slalom, pump track, downhill, and advanced skills.


Format: This program is focused on learning more advanced gravity skills including hitting jumps, riding off drops, cornering on berms, wall rides, and wheel lifts like manuals and wheelies. For the more advanced students, we will work on jump tricks like whips, tables, one-handers, and x-ups.

Trails will include Voodoo Child, Jubilane, and Gravy Train. For more advanced students we will ride Double Trouble, HLC, Semper Dirticus, and Flying Squirrel.

signing up for the wrong level

We understand that students may grow their mountain bike skills, or have a crash/injury that diminishes their mountain bike skills, between signing up for camps in February and attending camps in the summer. However, there are some situations in which a student has abilities far outside the description of the level they were signed up for and cannot be safely accommodated. In these situations, the student will be unable to attend camp and will not receive a refund. It is essential that parents thoroughly review the level descriptions before signing their child up for camp to ensure they pick the correct level.


Masks are not required this summer!

Students will not be permitted to attend Sweetlines camps or events after a positive Covid test until at least day 6 of their illness, with their first day of symptoms as day 0. This is in accordance with national, state, and local Covid-19 guidelines, which state that people who test positive for the virus that causes Covid should isolate for at least 5 days. Some circumstances will result in a longer isolation. Please refer to this information page from the CDC, which describes our policy in detail: LINK HERE

Additionally, please do not send your child to Sweetlines camps or events if they have symptoms of any illness (unless these symptoms are consistent with a non-communicable chronic condition your child has). Sweetlines students must go 24 hours free of severe symptoms (fever, difficulty breathing, vomiting, and diarrhea) before they may attend Sweetlines camps or events.

If you have any questions or concerns, please reach out to

Thank you for helping keep our Sweetlines community safe!


Heat (High of 95 degrees to 99 degrees): If weather predictions list the high temperature of the day to be 95 degrees to 99 degrees, camp for the day will be moved earlier by 2 hours. This allows most of the riding to be done in the cool hours of the morning and reduces the risk of heat illness in our coaches and campers. For example, if camp is scheduled to be 10:00-3:30 normally, it will be moved to 8:00-1:30. 

Severe Heat (High of 100 degrees or higher): If weather predictions list the high temperature of the day to be 100 degrees or higher, camp for the day will be canceled.

Smoke and other air pollutants (AQI): If the air quality index is green or yellow (0-100), camp will continue as normal. If the air quality index is orange (100-150), camp will continue but may be shortened and the amount of riding during camp will be limited. If the air quality index is red or purple (150 or higher), camp will be canceled. This is in accordance with CDC guidelines for childcare, which can be found here: LINK HERE.

Rain and cold: Sweetlines summer camps are very unlikely to be canceled due to rain or cold. Instead, decisions will be made on an individual case-by-case basis. If a child is too wet, cold, or uncomfortable at camp, parents or guardians will be contacted for early pick-up. We encourage parents to pack lots of warm and waterproof layers for their child on cold and rainy days! (Pro Tip: toe warmers work great in gloves and on top of toes in shoes.)

Lightning: Sweetlines camps will be canceled if a thunderstorm is in the forecast. If a thunderstorm rolls in unexpectedly, safety measures will be taken at camp and parents may be called for early pick-up. 

Cell phone policy

Cell phones at camp may only be used to take videos of riding or for contacting parents. If a student uses their cell phone for any other reason, they will not be permitted to bring it to camp. 


Inclusivity has always been a core value for Sweetlines. Kat Sweet began her mission with hope to bring more females to the sport, which now extends to all genders. At the core of her mission is inclusivity; we strive to deliver inclusive and accessible camps for all. We are working towards a future where everyone, no matter their background, such as age, race, color, national origin, religion, sex, sexual orientation, gender identity, or disability, feels they too can learn to ride mountain bikes and be part of our community. We are always trying to improve our practice so please share your expertise, feedback, and comments with us. For participants who may need accommodations, please give advanced notice to ensure that we can provide an optimal experience.


As long as you cancel two weeks (14 days) prior to the program start date, you will be refunded the full amount minus a $25 processing fee. No refunds for canceling within two weeks of the program start date. Programs happen rain or shine, but we may cancel if there is extreme weather (refer to heat and other weather policies above).


If you have been affected by Covid-19 or would like financial assistance to come to our programs for any other reason, please fill out this application and we will contact you to find out how we can help make that happen.
