About The Mermaid Half Marathon San Diego

The Mermaid Half Marathon San Diego in San Diego, California on 25 February, 2023 is a truly enchanting experience. The race route takes runners along the beautiful San Diego coastline and through Balboa Park, offering stunning views of the ocean and city skyline. This 13.1 mile journey has something for everyone – there are flat sections for speedsters to reach their personal bests, as well as hilly patches to challenge those seeking an intense workout.

For those running this event come late February in 2023, they can expect mild temperatures typical of Southern California with highs around 65-70F (18-21C). Although it may be cool at first light, most races start later in the morning when conditions become more comfortable. Participants can also look forward to cheering crowds lining up along much of the course who will help spur them on during tough portions.

The Mermaid Half Marathon offers plenty of perks that set it apart from other similar events – starting with its unique ‘Mermaid Mile’ where participants get fully outfitted with a mermaid tail finisher costume at mile 12! Additionally there are ample aid stations throughout the race stocked with water and sports drinks so runners never have to worry about dehydration or cramping up during longer distances; plus post-race entertainment such as live music acts and beer gardens keep things lively after crossing the finish line!

In summary: if you’re looking for an exciting half marathon that combines gorgeous scenery with challenging terrain while still maintaining a fun atmosphere – then make sure you sign up for next year’s Mermaid Half Marathon in sunny San Diego!
