Just came back from a pleasant beach running holiday on the Mediterranean island of Crete. It was beautiful and not too crowded this time of year. Most of the tourist attractions were still closed, which was just fine for me.
I ran, jogged and walked every day by the seaside, covering probably slightly less than 100 miles per week. No worries, it surely felt challenging enough as beach running requires a lot more energy and concentration than road running.
The weather was perfect with daily high temperature slightly above 30C (70F). The terrain varied greatly from fine sand to gravel, pebbles and rocks. Occasional delights included ice-cold river crossings, ankle deep mud, slimy sea rocks, and sharp volcanic terrain.
I ran mostly in Brooks ST racing flats, or simply barefoot. I saw some sea urchins, but luckily didn't step on any. Post-run cooling down in the sea was great for recovery.
I ran mostly on the wet firm sand close to the sea, between the waves and the soft dry sand. It's a very tricky thing to do because there is always the danger of getting your feet wet and then filling your shoes and socks with sand.
