"When I test I never go right to the limit. Only because when you are below the limit you can go at the same speed all day, and that's the only way you can be absolutely sure about what you are testing."

The beauty of running is its simplicity; the beauty of runners is that we all have a similar drive to improve. We are either trying to run a personal best, or toeing the line for the first time, which will snowball into a future of trying to run personal bests. We road racers are a tight community of mileage-happy, limit-pushing athletes.
