A challenge should be achievable but with the risk of failure. A little while back I set myself a long term target of running 100,000 miles before my 65th birthday, and when I calculated the weekly average mileage it was indeed achievable. In fact very achievable.
Last week saw my grand total of miles ran reach 89001. Although still on course to reach my target it is becoming, thanks to one injury after another, illness and to be honest a lack of motivation, just that bit more difficult.
But just one good run can change all that. Last night I ran a good 8 miles along the River Tyne to the Redhuegh Bridge and back through Dunston to Blaydon. The pace was good and I felt strong, only fading slightly over the last quarter of a mile.
So it's back to it, with that 100000 mile target once again looking very achievable.
