OUT OF THE By BOX Norrie Williamson RUNNING DRY A considerable number of races this year have run out of water at the refreshment stations, leaving runners without water for significant distances. Being short of water is unacceptable, that is not a debate, but what are some of the factors and changes happening in the sport, and why has this become an ongoing concern? In terms of IAAF guidelines, races should provide 1.5 containers of 180ml to 300ml per runner per station. This effectively requires an organiser to have a minimum of 750ml per hour for a five-hour marathoner. In South Africa, the current requirement of three sachets per runner per table typically provides a five-hour marathoner with 900ml per hour (assuming around 110ml per sachet). This does allow for some use for showering or cooling, but within reason. Dehydration Issues Clearly, when insufficient fluid is provided, a runner will suffer from dehydration, and there are thousands of references to the effects of dehydration in running. In many papers, a figure of just 2% dehydration is linked to a significant loss of performance. There are also many articles and references to risk of heat stroke and even death as a result of dehydration, but these are in fact predominately incorrect. At the very outset, let’s be absolutely clear that only a masochistic race organiser would try to make financial savings from ordering a few thousand less sachets of water! At around R400 per 1000 water sachets, it is unlikely to be an item that any organiser would look to cut back on to make financial savings, whereas consider some comparable items: • A standard 2m fence costs R40, so save 10 panels of fence and you have bought another 1000 sachets. • Or take a timing mat off the route and you can save say R25,000, depending on the system used and number of runners. • Even reducing the Coke and energy drinks can allow a significant proportional increase in water volume at a table. Consider that the total cost of water for the entire Comrades Marathon may look large at around R1.2- million, but cutting a couple of thousand sachets on a 28 table can see the whole race spiral into a frenzy of dry tables and dire consequences. No, water is the very last thing to be sacrificed by any knowledgeable organiser, so let’s kill any suggestion that races reduce water to save money. There have been moves, particularly in the Western Cape, to reduce the number of water tables, due to overall water restrictions, but this is an entirely different matter, and is as much to do with environmental issues and a required change in runner approach and ethics. It has zero to do with finances. Rules to Follow Of course, there are international rules on the provision of water in road running events. IAAF rule 240 requires refreshment tables at 5km intervals, and suggests additional points between this based on adverse running conditions, fitness of participants, and the distance of the event. ASA rule 34.8 stipulates a 3km maximum interval in mass events. Various provinces have implemented even tighter restrictions due to adverse conditions, in particular KZN, where since the mid-1980’s tables have been required at 2.5km intervals due to heat and humidity, particularly from November to April. It is only the drought in the Western Cape in recent years that initiated a move to 4km intervals, and calls for runners to bring their own water to races. ISSUE 118 MAY 2019 / www.modernathlete.co.za I am fortunate to be based in Durban with one of my favourite runs a 15km to 20km along the low tide beach between Blue Lagoon and the harbour mouth. There are no water points on the beach and I rarely stop other than to climb through or over the piers. This run, if taken as a low heart rate fat metabolising pace, is easily handled without any drinks whatsoever, even with the heat and humidity. This is what we humans were ‘designed to do’ when hunting down animals in our heritage. Interestingly, when I feel hot, simply running a few steps in the water and allowing my shoes to get wet virtually instantly satisfies the need to drink, as the brain detects the cool water and counters the previous signals of heat. The exceptions to this are those runners who compete while on medication that provides some form of signal-blocking to the brain. S outh Africa has a long history of well-organised road running events that match the best in the world, and the country has been at the forefront of many organisational innovations. So why now are several well-established events running short of water? What has changed, or are people trying to make savings in water at the risk of dry tables? The research from Professor Tim Noakes is too long to explain here, but as detailed in his two books, Waterlogged and Challenging Beliefs, it is now acknowledged that runners will not die of dehydration, because the ‘self-preservation’ signals from the brain will take control and result in the body being slowed, or even forced to stop, in order to prevent any self- destructive actions. In fact, Noakes points out that the risk of heat stroke is greater in a short, intense race in hot conditions, than it is in a marathon or ultra, because the intense effort and expenditure of energy create greater internal heat, with less opportunity to be dispersed, resulting in the core temperature increasing.
