Bloody hell Prue, you're too old for this falling-over nonsense. Are you sure it's just tiredness, and not an inner ear/balance thing?
Or not being able to see.
Maybe O is not the right activity for me :(
There's this great new invention called Spectacles. They sit on your nose and let you see things...
Maybe the glasses are the problem? I stopped wearing mine (to read the map) because they made judging where I was putting my feet too difficult. My dad would say: trifocals are the answer!
I think the problem is multi tasking, which is unfortunately an essential skill for successful orienteering. I trip when l'm doing 2 or more of running, reading the map, looking ahead and not at my feet, cleaning my glasses or wiping my eyes. I tend to relax a bit on tracks and do all these things and therein lies the problem. I'm a bit more careful in the bush.
One contact lens plus head band removes the cleaning of glasses and eyes task.
Yes, maybe time to try that.
