June 2010 Back to Table of Contents Better, Stronger, Thinner, Faster?A WEIGHTY QUESTION. Many people run to lose weight. In fact, weight loss is often cited as the most common reason adults start running. Once a runner is hooked on running they may look at weight loss as a strategy to run faster. Over time, weight loss becomes a means to a goal and not the goal. Will losing those stubborn last five or ten pounds really make a difference in your next 5k race? What about your next half-marathon? Watch a race and you quickly realize that successful runners of all shapes and sizes proudly cross the finish line. You do not need to be a certain height or weight or build to be a decent runner. Still, there is no denying that the world’s elite distance runners have one glaring physical characteristic in common. They are small-framed and very lean. NO MAGIC BULLETS. The danger in advocating weight loss as a performance enhancer is that it can lead to unhealthy temptations. Quick fixes. Fad diets. Restriction cleanses. Pill popping. Ill-advised weight loss won’t speed you up. Quite the opposite. Ten days on the maple syrup cleanse may sabotage your best efforts at a new PB. It should go without saying, but it is worth saying anyway: any weight loss must be part of a sensible and nutritious dietary plan. Moreover, there must be extra weight to lose. If a person is underweight or at a healthy weight, there is no additional benefit to be gained by shedding a few pounds. Underweight by conventional BMI standards, I would run the risk of hurting my performance, not to mention my health if I tried to speed up my marathon times by losing five pounds on the grapefruit diet. With those disclaimers in mind, dropping a few pounds of surplus body fat may help you post faster race times than you would see at a heavier weight with the same training regime. Ah ha, another catch. Weight loss alone is no magic bullet. You can’t escape the training. One second per mile per pound does not sound like much of a bonus, but those seconds add up over the long run. As the weight loss and the distance increases the time savings are impressive. It is tempting to look at the table and start subtracting minutes from your PBs. Ten pounds to the Boston Marathon! Two pounds to a sub-40 minute 10K! The trouble is - and there’s always trouble - weight is difficult to separate from any number of performance factors. Genetics, environmental conditions, nutrition, sleep, health, training and countless other variables too numerous to list are all mixed up into a package that will determine your finish time on any given day. A bit of weight may make a difference, but all that other stuff matters too. Maybe matters more. WHY IS LIGHTER FASTER? When it comes to racing, we control what we can. If losing weight will help, even if it isn’t a magic bullet, it is an appealing plan. Every season on The Biggest Loser the newly slimmed down contestants are forced to participate in some sort of challenge that requires them to carry around weights equivalent of their total weight loss. If they lost 100 pounds, they wear a 100 pound weight vest. The strain is evident immediately. It takes a lot of effort to move that extra weight. Their breathing becomes laboured. There is less spring in their step and slower turnover in their stride. Their knees and backs hurt. They slow down. In short, it’s hard to move. Matt Fitzgerald, in his book Racing Weight: How to get Lean for Peak Performance, sums up the thin advantage nicely: body fat adds very little to performance (it may serve as a limited fuel source), but that extra fat increases gravitational resistance, decreases aerobic capacity (V02max), and increases thermoregulatory strain. You don’t need to remember high school physics to appreciate that mass and resistance are not a friend to runners. SKINNY IS AS SKINNY DOES. With all of these factors in mind, however, it’s important to remember not to feel limited by your size, especially if your finishing times are improving regardless of what the scale says. Finishing order is not determined by weight - if it were, there would be a lot more supermodels moonlighting as elite marathoners. Think about that next time you pass someone who looks like they belong in the elite division. HOW MUCH FASTER IS FASTER? You’ve read the disclaimer, you have a bit of weight to lose, and you set a realistic weight-loss plan. How much speed can you hope to gain as the pounds melt away? Drawing on an equation widely attributed to Tom Osler in The Serious Runner’s Handbook, most experts ascribe a two second per mile benefit for every pound lost. For the metric runners, that’s about 1.25 seconds per kilometre. The formula can be faulted as overly simplistic, but we can use the numbers for illustrative purposes to show the kind of time you could save over various distances:
