The fear: Getting injured
The fix: Train smarter
What is a runner's number one fear? Injury, according to two-thirds of RW poll respondents. Start winning your battle with the injury demons by increasing weekly mileage by no more than 10 per cent, separating long runs, tempo runs and speed workouts by at least 48 hours, and understanding that more isn't always more. "There is evidence that clocking over 45 miles weekly can increase injury risk," says Dr Evan Teplow, running injury specialist. He also advises running on soft surfaces and replacing your shoes every 500 miles. No guarantees, but lower odds of injury.

The fear: Not losing weight
The fix: Check your diet diary
Running does burn calories. Lots of them, in fact. It also increases your metabolic rate for 14 hours after you stop, according to a study published in Medicine & Science in Sports & Exercise, so you're still shedding lard when you're snuggled on the sofa. But that doesn't mean you can eat like a sumo wrestler. "Some runners overcompensate by routinely treating themselves to big meals or desserts, thinking the extra calories they've burned justify it," says Dr Laura Kruskall, a sports nutrition specialist at the University of Nevada, US. "Unless you do a long run, it doesn't." Despite evidence of carb intake boosting performance before, during and after running, you'll add pounds if you overdo it. "You don't need extra carbs for runs of an hour or less." If you have run long, on the other hand...

The fear: Trail dangers
The fix: Plan ahead
Have you been watching 127 Hours by any chance? Getting in trouble on an out-of-the-way trail is a rare scenario, and self-amputation thankfully rarer still. However, you can use your fears as a positive spur to take the simple steps required to make it even less so. "Firstly, map out your route before you leave home," says Justin Walk, a running coach in the trail Mecca of Colorado. Ideally don't go solo, take a mobile phone with you and consider upgrading your gadgetry to include GPS and OS mapping capability.
As for injury, twisting an ankle is the likeliest scenario, but you can make it less likely if you improve your on-the-run balance. Twice a week, reach slowly to touch your left toe while balancing on your left leg, repeat 10 times, then switch legs. To avoid falling on trail runs, take shorter strides and keep your eyes a couple of metres ahead to spot protruding roots and rocks.

The fear: Fading with age
The fix: Set different goals
"Everyone slows down eventually because aerobic capacity drops off as we age," says Jeanne Hackett, a running coach who also has a master's degree in counselling psychology. "Once you've run your last personal best, you may have half a lifetime left. So if you choose to stay in the running game, you need to renew and review your goals." One way to do that is to set age-based time goals each year. Try to beat the best time you've run for each distance while in the 45-49 age group, for example, or aged 47. View the statistics as narrowly as you like. And if you still crave a lifetime best, enter a triathlon, or a road race at a new distance. Or get a watch that's slow.

The fear: Catching a cold
The fix: Relax and sleep
Running should make you less prone to illness because it boosts the immune system, helps you sleep better and reduces stress. So why do some runners get colds all the time? Perhaps they set the alarm an hour earlier for daily morning runs or do marathon training while putting in marathon working weeks. "Research has shown that both lack of sleep and frequent periods of high stress can severely reduce immune function," says immunology specialist Dr Laura Stewart. "One of the best ways to reduce the risk of upper respiratory tract infections is to be sure you aren't overtraining. Moderate exercise reduces this risk, but speedwork, long runs and races appear to increase it." It's also believed that the more intense the workout, the longer and greater the immune system is suppressed - one more argument for having easy or rest days after these sessions.

The fear: Not running again
The fix: Diversify
Not ever being able to run again is a fear that torments absolutely everyone who loves running. "It can seem irreplaceable," says behavioural health consultant Joyce Hanna. "But it's not the only thing that can give you that exercise high." Taking up new and diverse activities - such as swimming, cycling, yoga or strengthening classes such as Body Pump - now is insurance in case you ever have to stop running for health reasons. The bonus is that cross-training gives your body a welcome break from the impact stress of running, so it can also extend the longevity of your running lifespan and make you a better runner in the short term.
