Lost gold chain necklace with a tiny heart-shaped pendant near the Riverwalk in Tampa Bay Area.

I lost my gold chain necklace with a tiny heart-shaped pendant while I was jogging in the Tampa Bay Area near the Riverwalk. I remember feeling it slip off during my run and unfortunately, I couldn't find it after retracing my steps. It holds a lot of sentimental value to me and I'd really appreciate any help in locating it.
