I recently moved close to the beach and have found what I think is a very good workout: running in the sand! It seems great for building leg strength and is a lot more difficult than running on solid ground so it provides a great cardio workout. I do have a couple of anal-retentive questions for those who might have done it in the past:
1. Could there be any issues with injury? It seems to me that running in the sand would actually be easier on your body due to the cushioning effect of the sand. However, I just want to check to see if perhaps there is something I'm not thinking about.
2. Would it be better to run barefoot or with shoes on? I'm leaning towards barefoot as it seems to me that going barefoot builds more strength in the tendons as you don't have all the support a shoe there. The only downside I can see if maybe catching an occasional piece of glass in my foot but I think I can live with that possibility.
