Balboa Park Beginner Ride

Morley Field Sports Complex

Welcome to the Beginner ride at Balboa Park! This group is geared towards new riders getting comfortable with their mountain bike and dirt trails. Also for the riders returning to the trails and need to get their fitness back or want to explore new trails.

We will meet in the parking lot (see the map) and ride out to the trails together.

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 5pm - 6:30pm, with frequent stops to regroup and to work on skills. Average distance is 5 - 8 miles with ~200ft elevation gain.
With the days getting shorter, it's time to light up.
Light recommendations:
These are good for either handlebars or Helmet. Get at least 900 lumens and up to 1200 lumens is good.

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.

All participants need to complete the SDMBA waiver at least once every 6 months. SDMBA Waiver

The ride is lead by Karen St.Germain.

Trail Maintenance: Mount Laguna - Gatos Ravine - rockwork for water drainage

SDMBA trail maintenance on the Laguna Rec Area, Noble Canyon Trail and surroundings have been graciously supported by Cal Coast Bicycles for countless years.

Cal Coast Bicycles will have more swag to hand out throughout the year!

Location: Sunset trail head, across the street from the port-a-potty. Adventure pass required.

We will be closing off short cuts, narrowing widened trails and cleaning out drains just downhill from the Chico Ravine connector on Gatos to amplify the final downhill section pucker factor.

We will be moving very heavy logs and heavier rocks to control water flow and drainage issues.*

If you have seen the work we have done, then you know. If you have ridden Gatos lately, then you know.

Bring bicycle, own snacks and water, work gloves, protective eyewear, covered footwear. We will ride to work site, swag, snacks after.

No walk-ups. We take your RSVP here as a confirmation that you will show up. If something unexpected comes up or you feel ill before the event, please email Brian at [masked] so we can fill your spot.

Cell phone reception is spotty at best at the trail head. Usual travel time from La Mesa to trail head is approximately 1 hour.

Inclement weather or unsafe conditions will cancel this event. Updates will be posted in comment thread on this page.

Signed SDMBA Waiver 2 pages including self-health questionnaire - print out and bring with you or we will have hard copies: https://drive.google.com/file/d/1B95Tj7L3n5IUyo4PdnoxZ0ip92OmmJmF/view?usp=sharing

-Sanitize frequently

We have worked with our land manager partners to ensure that all volunteers and staff will commit to these protocols in order to ensure the safety of everyone during COVID-19.

We appreciate your dedication and commitment to safety during this time. Please email me directly if you have any questions - Brian Suzuki at [masked]
