MTFMR – Movement to Forward Movement Ratios

movement to forward movement tranlations

As you know, in the Eowyn Challenge, all self-propelled forward motion counts toward your journey.  That means translating 1-to-1 as far as miles. So swimming, rowing, skating, biking, walking, running, etc. are all 1-to-1 and figured out by time. Interestingly, the hobbits have been working in conjunction with some very clever people to create a vehicle which can not only traverse terrain but water too. It hovers in the air you see. (Well, admittedly Gandalf provided a bit of wizarding.) It’s truly amazing because it translates any kind of movement to forward movement which, when speaking of health and life, indeed, it is! It is estimated that the amount of sweat effort and movement ratio is very personal but easy to figure out.

Here’s how you do it (you can skip to the end for the bare math formula if you don’t need a description):

Meandering movement  (mtfmr2)

How long does it take you to walk a mile if you were to do it in a meandering way? It would be the kind of walk on a sunny day that doesn’t cause you to sweat or lose your breath. Let’s say it takes you 20 minutes. Well if you stand in this contraption and you do any kind of movement for 20 minutes that doesn’t cause you to sweat or lose your breath (perhaps that stretching breathing bending thing I heard the elves do) then even though you aren’t moving forward, the contraption is. In 20 minutes of light movement you will have gone a mile. Let’s call this a movement-to-forward-movement-ratio (mtfmr) of 2 since standing still is a 1.

Purposeful movement (mtfmr3)

Now suppose it takes you about 15 minutes to go a mile if you walk purposely, arms swinging — the kind of walk you do when you know there’s fresh-made pie at the bakers or you’re meeting friends at the lake. You sweat a bit, maybe breath a little bit heavier, but you aren’t too bothered by the walk. If you do the same kind of movement while in the Hobbit-Forward-Movement-Contraption (HFMC) for 15 minutes, you will have gone a mile! This is a mtfmr of 3.

Fast movement (mtfmr4)

Now suppose you hear that Gandalf is about to set off fireworks. You want to get there really fast. You go very quickly now, and you are sweating a lot. Your arms are pumping. It takes you only 12 minutes to get to that lake now to see the fireworks. If you were to do that kind o vigorous movement in the HFMC, you would have gone a mile in 12 minutes. This is a mtfmr of 4.

DRAGON! (mtmr5)
There is one other kind of movement that you rarely do. This is the kind of movement you do when you are at the lake having a picnic with your friends and, across the water, you see a dragon heading your way. This is as-fast-as-you-can-move movement. If you took the time to get into the HCFM and move exactly as fast as you are running from the dragon, you might discover that you would go that mile home and dive into your cellar in 10 minutes! This is maximum effort movement and has a mtfmr of 5.

Now everyone will have a different number. The way to calculate that is to figure out how hard you are working. It might take you 20 minutes to walk a mile in a meandering way, but it would take someone else 20 minutes at maximum effort to go a mile.

Once you know what your mtfmr number is, you can figure it out by intervals too. Say I am standing in the HFMC and I want to move at different efforts for 25 minutes. In each five minute segment of time, I would move from an mtfmr of 2 for 1 minute, 3 for 1 minute, 4 for one minute, and 5 for one minute.

That means in 20 minutes I will have moved at 2, 3, 4 and 5 for 5×1 minute each, or five minutes each.  I asked a very gift (math) wizard for a formula (thank you Chip!) and here it is:

The formula you want is:  (distance) = (time) / (speed)

…where speed is the number of minutes it takes to go a mile at each intensity level.  Your math was mostly right, except for mtfmr4:

mtfmr-2 = 5 minutes / 20 minutes per mile = 0.25 miles

mtfmr-3 = 5 minutes / 15 minutes per mile = 0.33 miles

mtfmr-4 = 5 minutes / 12 minutes per mile = 0.416 miles (round to 0.42)

mtfmr-5 = 5 minutes / 10 minutes per mile = 0.50 miles
So in 20 minutes of 4 intensities as described in the above example, your total distance would be 1.50 miles (0.25 + 0.33 + 0.42 + 0.50).
