How well are we equipped to run? - 4. Evidence from our achievements April 29 2016, 0 Comments

So are we designed for long-distance running?

Apart from the anatomical evidence that we have discussed in the previous instalments (1, 2, 3), if we look at what we achieve as a running species, it becomes impressive.

Vast numbers of people participate in marathons and half marathons all over the world.  It is gender-neutral. Men's and women's marathon records get closer year by year, and are now within 10% of each other. If we are looking at distance running, then a marathon could be construed as a bit short. Very long races are run on every continent, including the Bruce Trail (Canada - 800km), the Bunion Derby (USA - 3'455km over 3 months), the Ultrabalaton (Hungary - 220km), the Trans-Europe Foot Race (last run in 2012, 4'175km in 64 days) and the Big Red Run (Australia, 250km in 6 days in the Simpson desert).

Dr Dennis Bramble ran an exercise to plot the age of all participants in the New York Marathon against their running times. He found that speeds increased from the age of 19 up to about 27 years of age, and then they declined. Although this might be expected, the rate of decline was very slow, and it was not until an age of 64 that the speed had declined to the same as the starting point of 19 years old. If you think about it, if you need to chase your food for 60km, you're not going to want to lug it back home, and so the whole tribe has to follow dinner until it lays down - so the ability to run has to be long-lived.

Finally, in a long-distance race between a man and a horse, which would you back? It's an interesting question because the stride of a good runner is longer than that of a horse, and we have already established that we can do distances. Since 1980, this event has taken place in Wales each year over a 22 mile (35km) course. The horses win more often than the runners, but the differences are not huge, and on two famous occasions, both on hot days, the runner has won.

So we appear to be designed do long-distance running. Moreover, we increasingly do it for fun, suggesting that we are following a natural instinct to run, and we have developed as a running animal in an evolutionary laboratory over 2 million years. ZEMgear shoes allow us to indulge this ability in a way closest to the natural barefoot state, protecting our feet and still allowing us the flexible, natural use of our feet.

Running inspiration September 22 2015, 0 Comments

I did the Greifenseelauf last weekend. It's a half-marathon run around the Greifensee lake here in Switzerland, relatively tame by Swiss standards because it is nearly all run on the flat, but a great opportunity to watch runners in action.

The run starts in a hubbub of excitement with each stage (there are 17'000 runners, so it needs to go off in stages...) setting off with an abundance of chatter and banter amongst the competitors, and with a few burning off into the middle distance either to achieve a fast finish or to be passed later walking. By about 10km most have settled into their quiet little world of contemplation and the rest of the run is conducted in silence. My own contemplation was about how running really is a community within which there is a diverse spread of inhabitants. Being in the barefoot shoe business, I pay attention to the footwear. There is a growing number of barefoot runners, ranging from the more conventional round-toed, lace-up variety through ZEMgear Ninja-Toe and Vibram Five Fingers to one runner who was wearing huarache sandals. There was even one pioneering soul who had gone back to absolute first principles and was running barefoot - I started this way, but chickened out when the cold weather arrived and switched to some nice snug ZEMger winter shoes.

But I digress - we were talking about the running community. If you go to YouTube and search for 'runner helps', you get over 40'000 hits. Many of these are codswallop, but amongst them are some truly wonderful stories. One of the most famous is Derek Redmond who had to stop running with a painful hamstring injury in the 1992 Olympics 400m final, but who got up and hopped on to finish the race, helped by his father who evaded the security people to get to his side. In long distance running, Ivan Fernandez deserves a mention for slowing down to tell his disoriented leading competitor where the finish line was and allowing him to cross first, or Meghan Vogel, who stopped to pick up Arden McMath, a competitor in trouble, and helped her across the finish line. There are many more, and they both inspire, and make me glad to be a part of this remarkable community.
