Navy Nike running shorts, size M, white side stripes

I lost my navy blue Nike running shorts, size M, near East Beach in Santa Barbara yesterday around 3pm. I was jogging along the Cabrillo Boulevard boardwalk when I must have dropped them on a bench by the lifeguard stand. The shorts are Nike with white side stripes and the swoosh on the left thigh; there's a small teal stitch near the waistband and a faint coffee stain on the back pocket. They're slightly faded from repeated washes but still in good condition. They hold sentimental value - they were a gift from my sister, and I really need to get them back.
