People love to run along the beach, so why not at sunset? And can there be a better location for running than Tamarindo Beach at sunset? It is broad, gently sloped, not crowded, and the boats in the bay bob up and down with the waves while silhouetted against the crimson sky. Pelicans occasionally dive into the surf for fish.
And for those who are there not to exercise but simply to enjoy the view, well, I am sure that they do not mind having their view of the sunset interrupted by the form of a physically fit runner moving across their field of vision.
