50 Mile: 6:30AM
Marathon Mandatory Check In: 6:30 – 7:15AM

Mandatory Check In: Even if you picked up your packet prior to race day, it is MANDATORY that you check in prior to starting the event. This will allow us to know who is out on the course and helps ensure your safety. Anyone that starts the race without checking in first will be disqualified. 

EARLY START NOTE: Early starters must announce their intentions to start early to the Race Director via email prior to race day, please email [email protected] Participants opting for the early start will not be eligible for overall or age group prizes and will have their results posted separately. Be sure to check the Aid Station Opening Times and be prepared to carry enough nutrition and hydration in the event you pass the first few aid stations before they open. Participants wishing to use the SD50 as a qualifier for a future 100 mile event MUST start at the 6:30 time and finish under the 13 hour cutoff. 

Drop Outs
Any drops that happen during the race must be immediately reported to the aid station captain. Upon dropping out, please turn your bib in to the aid station. Anyone dropping out without notifying the aid station will be disqualified and banned from future Off Road Pursuits events. This action can result in costly search and rescue efforts and is taken seriously. Please don’t make your volunteers spend all night searching for you when you are home on the couch!

Time Limit
There is a 13 hour time limit for the 50 mile event with intermediary cutoffs at aid stations.

Headlamp Requirement
Sunrise on race day is 6:51AM, whether you are starting in the early wave or standard wave for the 50 Mile, you will benefit from a headlamp for the start.  Sunset is scheduled for 5:06PM. If you will be running after 5PM, you MUST have a headlamp or flashlight to be allowed to continue.  Aid Station volunteers will not allow you to continue running without a light source after 5PM. If you do not carry a headlamp from the start, be sure to have one in your drop bag at the Bing Crosby Aid Station.

Hydration/Nutrition Requirements
All runners are required to carry a minimum amount of hydration with them throughout the event. Marathon participants must have no less than a hydration belt (10 oz) and 50 Mile participants must carry at least a 20 oz Hand Bottle throughout the event. These can be substituted with various belts, packs, bottles that best fit your running needs but all participants must carry their own fluid container. This not only helps ensure your safety and performance on the course but helps us cut down on waste and keep the event as green as possible. 

Aid stations will be well stocked with water, electrolyte drink, gels, snacks and salt tabs. However, it is STRONGLY encouraged that you carry your own salt and gels and use the aid stations to supplement as needed. Again this is to best ensure your safety and performance on the course and cut down on waste. 

Littering Restrictions
This event is being held with the cooperation of the San Dieguito River Park and Black Mountain Open Space. These trails are fantastic multi-use trails meant for the enjoyment of the entire San Diego community. DO NOT trash the trails. Anything you carry with you from the start can be carried to an aid station. Anything picked up from an aid station can be left there or carried to the next. Anyone seen littering the trails will be IMMEDIATELY disqualified, will not receive an official finish result and will be banned from all future Off Road Pursuits events. If you see someone drop something, let them know so they can go back and pick it up. If they do not, please alert the next Aid Station. There isn’t much I take seriously in life but the care and preservation of our trails is one of them. Pack it in, Pack it out!
