Yesterday, I was in Hermosa Beach for a party reuniting old friends and it was a wonderful time. Had I thought about it more, I would have, (you all remember woulda, coulda, shoulda?) gotten there earlier and drove one beach city over to Manhattan Beach to do a sand dune workout.

What prompted me that it’s time to hit the dune again was an article by John Berardi and Scot Prohaska titled “Indecent Intervals” where they outline their experiences and interval workouts with the famous sand dune.

If you can’t make it to the sand dune for the intervals, you’re not off the hook. Berardi and Prohaska share 4 more gut-wrenching interval workouts every bit as challenging as the sand dune.
