15 mile hike today, i'm a slow walker,cbut pushed it so was going at 5.35kph which is seriously fast for me I'm a lazy cow, and my normal walking pace is 4.2-4.3kph so the extra effort was hard work. 4.5 hours. Knee ached a bit but feels ok now I've stopped.
I was lazy n wimped out!! Spec savers had some wrap around ones for £79 including lenses so just couldn't be arsed to mess around and got two pairs of glasses with transitions lenses and a pair of them.
