Sri Chinmoy San Diego 6-hour Race

For the duration of the event, athletes traverse the 5-mile loop around the lake, moving in a clockwise direction. In the last 30 minutes, participants who reach one of the three remote aid stations are credited for this additional mileage. These locations are located 1 mile, 2.5 miles, and 3.5 miles from the Start/Finish area. 

As is common in timed events like this one, athletes may choose to stop at any time before the 6-hour cut-off. For example, if you complete a lap at 5 hours and 20 minutes, you can decide whether or not to go further--you've already put in a great performance! Also, some participants may have a particular distance in mind--for example, a marathon--and may plan to stop at that point no matter how much time is left on the clock.

2026 Course Map 

The course is beautiful and unique--immersed in sights and sounds of nature and consisting of several "fingers" rather than just a round loop. Please note that all athletes must stay on the asphalt surface that encircles the lake. Although there is an off-road dirt trail at the lake edge, this is unmeasured and off-limits for the 6-hour race. Athletes who go off the certified course will be disqualified.

The asphalt loop will be shared with runners, walkers and bicyclists who are not part of the 6-hour race; cars with a permit are allowed on the road but typically there are very few and they're required to drive slowly. There is plenty of space along the course. A yellow center line divides the road. Regardless of what direction runners/walker/bicyclists are heading, they must stay to the right of the yellow line. The 6-hour race athletes will be running in a clockwise direction, hugging the lake.

There are permanent wooden markers located every 1/4 mile of the lake loop. Although these markers won't correspond exactly to our race course (because the start/finish line is in a different place), they're helpful  indicators of how far you've gone on each loop. (Race starts at the "1/2 mile" post; so, each time you see a wooden marker, subtract 1/2 mile from the distance shown in order to know the distance you've covered.) 

Lake Miramar has 4 permanent restrooms near the bait shop and pier (near main parking lot), which you will pass on each lap of the course. There is running water there, including a water fountain on the exterior of the building. Additionally, there are multiple portable toilets located along the 5-mile loop course--easily visible on the course. Each Aid Station has a portable toilet nearby. NEW for 2026: We plan to have an additional portable restroom at the Start/Finish Staging area for convenience of athletes and volunteers.  

The main staging area for the race is on the dam at the west end of the lake--about 1/3 mile from the entrance to the lake from Scripps Lake Drive. Please allow enough time to walk to the staging area and still have time to check in, get your race bib, store your gear, etc. The race will begin promptly at 7:00 a.m. Parking options for the event are off-site but not too far away. More specific parking instructions will be sent to registered participants (see also general info in the Transportation and Parking tab below).

The course will feature four aid stations--one large one at the main staging area and three smaller ones spaced along the course.

The main aid station will feature water, Skratch electrolyte drink, and a large buffet of food items suitable for the event (fruit, snacks, sandwiches, etc.)  The smaller stations will serve water and Skratch and some simple food (salty crackers, bananas, and a sweet item). 

Be sure to stick around for the hearty lunch offered free to all participants at the conclusion of the race!

Each aid station will have a trash receptacle for cups (or wrappers, gel packets, etc.). Please dispose all items ONLY IN THE TRASH RECEPTACLES. No items of any kind should be thrown onto the road or into bushes along the course.

Our aid stations provide cups but we encourage you to carry your own water bottle in order to cut down on waste. You can refill your water bottle at the aid stations. The permanent restroom building near the main parking lot has a water fountain where you can refill your water bottle if needed between aid stations.

At the main staging area there will be a section for your personal gear bags. You'll be able to access this area on every lap. We will have a few chairs there for athletes to briefly rest, adjust shoes, etc. We'll endeavor to keep this location reasonably secure but please do not leave valuable items there. Be sure to put your food items in a hard container so that the birds and chipmunks don't get to them while you're out on the course!

Our designated race physician, highly experienced in athletic events, will attend to general medical needs if  required. in the case of a medical emergency, we will call 911.

We trust that you can manage your own first aid such as blister care, cramps, etc. but of course we'll be there to help if needed.

if you do not plan to complete the full 6 hours, but would like to participate for a shorter time (or a specific distance), this is fine. Please inform us when you stop running/walking--tell the Race Director or a counter at the main staging area.

For example, let's say you want to complete a marathon and you reach this distance (26.2 miles) in 4 hours and 45 minutes. Please walk back to the staging area and inform the counters or Race Director that you'll not be doing any additional laps. If you cannot walk to that area, please call 619-251-6321 to inform us that you're no longer on the course.
