Ah. I didn't catch that part. Unless it's making money though...
As for actually achieving the Rutman Mile, the task is a 15:00 mile is a 1.0x BW sandbag (even 0.75x would be good), with a 15 second penalty for every time you drop the bag. (Hell knows why they penalize you for dropping it. I'd say having to pick it up again is enough punishment, but that's the way the challenge goes.) I've often seen it recommended that you shoot for the pace first, then slowly up the weight. This makes sense to me for two reasons:
1. Most people can't even shoulder a BW sandbag initially, let alone walk with it.
2. Doing a slow, but heavy, sandbag walk with a lot of breaks will give you a very limited cardiovascular, so it'll take you a long time to get not only the pace you want, but the ability to maintain it.
If you agree with the above reasons, go for the pace first. At 16:00, you're not far off anyway. Did you have any drops in your first attempt?
