Did the Bataan Memorial Marathon Sunday. Civilian -Heavy....rucked a 39 lb (they weighed it) pack for 26.2 scenic miles through the New Mexico mountains. Came in 82nd, my buddy was 9th overall - he seriously tore that thing up. Hardest race I've ever been in, nothing even comes close. Beautiful weather, scenery, I highly recommend fo anyone looking for a unique marathon/half marathon adventure. They have heavy (with pack) or light (no pack) divisions. Buyer beware - that pack really starts to suck by the time you're hallway through.
