See all- Balboa Park Beginner RideMorley Field Sports Complex, San Diego, CA
Welcome to the Beginner ride at Balboa Park! This group is geared towards new riders getting comfortable with their mountain bike and dirt trails.
All participants need to complete the SDMBA waiver at least once every 6 months. SDMBA Waiver
This is a no-drop, beginner paced ride around some of the best trails Balboa Park has to offer with time to work on some basic skills. The ride is from 5:30pm - 7:00pm, with frequent stops to regroup and to work on skills. Average distance is 5 - 8 miles with ~200ft elevation gain.
We will meet in the parking lot (see the map) and ride out to the trails together.
IT'S TIME TO LIGHT UP! Here are some light recommendations:
I recommend at least 900 - 1200 Lumens. One light for the helmet and one on the handlebars and a rear light on the seatpost.
NiteRider is really good and has internal rechargable battery.
Bright Eyes is also good but the rechargable battery is external.Mountain biking can be a dangerous sport, and learning new skills can be challenging. Always wear a helmet, bring plenty of water and if any part of the trail is above your ability and/or comfort zone it is okay to walk it.
The ride is lead by Karen St.Germain.
