Chasing Shadows

Gorgeous Bike ride today with my nz friend Helen , we did about 25 miles and it was so sunny and nice ...
I was fascinated as always by the way my shadow changes depending on which way we going but the fact that I can never catch it really bugs me .. I know it is science and i never will but it teases me and my competitive spirit comes out ..
Yes I know there is not any point trying to beat the shadow but thats irrelevant when you are there at the time .. TRUST me ..
