Yes.  For the half marathon, you must be able to complete the course in 3.5 hours. This means you must maintain a 16-minute-per-mile pace or faster.  For the 5K, you must be able to complete the course in 1 hour. This means you must maintain a 19:21-minute-per-mile pace or faster.

Both the half marathon and 5K time limits are based on chip time, meaning the time limit countdown begins the moment the participant’s timing chip passes over the start line timing mat.

Learn more about the course here.

  • Personalized bib number (if registered by March 27, 2020) and timing tag
  • A short-sleeve, top-quality, technical fabric men’s or women’s race shirt

Fully staffed and equipped water stations will be positioned along the course approximately every mile (2, 3, 4, 5.5, 7, 8, 9, 10, 11.5 and 12) with plenty of water and portable toilets. Nuun electrolyte replacement in flavor Lemon Lime Sport will also be served at approximately miles 2, 3, 5.5, 7, 8, 10 and 12. Please note that we are not permitted to have a support station inside Torrey Pines State Park.  There will still be one before and one after exiting the park.

If you experience a medical problem on the course, go to the nearest water station where a medical representative will be called to assist you. If you are unable to finish the race, shuttle transportation back to the finish can also be called from every water station. Race Guards trained in CPR and first aid will also be out on the course.

There will be a medical tent in the secure, fenced-in finish chute, just beyond the finish line.


To switch from the half marathon to the 5K, you may keep your same bib number and start your race from the 5K start area. There is no refund for the price difference. You will get an official 5K time once you cross the finish line.

To switch from the 5K to the half marathon, call In Motion at 760-692-2900. We will need your estimated finish time for the half marathon and your credit card number. NOTE: You must do this before the half marathon sells out and you will need to pay the difference between what you initially paid for your 5K entry fee and the current half marathon entry fee, plus the applicable processing fee.


All participants must pick up their own bib number with timing tag attached and race shirt at the expo on Saturday during regular expo hours. They will not be mailed. At the expo, you’ll first pick up your bib number (you must have your photo ID) and will then use your bib number to pick up your race shirt and cinch bag. While we do all we can to ensure you receive the shirt size you request, unfortunately, we cannot make any guarantees.

If you’re unable to attend the expo, you may authorize someone to pick up your items for you. This person must come with a photocopy or electronic copy of your photo ID.

Yes! Finisher medals will be awarded to half marathon and 5K finishers upon completion of the race in the finish line chute. 


Yes, there will be pace groups provided by the Road Runner Sports Pace Team.  Pace group leaders run a steady pace throughout the race so members of their group are able to finish the half marathon in the projected finish time for that group.  Pace groups with the following target finish times will be offered (times are subject to change):  1:30, 1:40, 1:50, 2:00, 2:15, 2:30, 2:45 and 3:00.


For your safety and the safety of your fellow participants, you are encouraged NOT to use iPods, MP3 players, or similar devices during the race. However, if you choose to use such a device, it is recommended that you keep the volume at a level at which you are aware of your environment, can hear course directions and any emergency situations which may arise.


No.  Since we implement a wave start for the half marathon, there are no timing clocks or split time callers on the course. If you’re interested in tracking your time on race day, plan to wear or carry your GPS/timing device.


We use a multi-wave start and your bib number will have your wave number on it. Everyone, regardless of his or her indicated wave number, must be at the race start line when the gun goes off at 6:30 AM. Any half marathon participant who starts earlier than the 6:30 AM starting time will be disqualified.


Yes. The La Jolla Half Marathon is run on a certified and sanctioned course.


The half marathon course is certified using USA Track & Field course measurement criteria employing the use of an Alan Jones counter. The course is measured along the shortest distance between the start line and finish line, which entails taking the straight line tangent on all curves. It is virtually impossible for anyone to run the course exactly as measured, even the front runners.

A GPS device measures distance wherever you go during the race. If you go to the side of the road to a water station, the GPS records this extra distance. If you zig-zag around other runners in the first few miles, the GPS measures the extra distance. Wherever you do not run the short line tangent in the road, the additional distance you cover is measured by the GPS. A GPS device worn in a race will always record a distance greater than an accurately measured course.
