This photo shows the start of the 10K road race and you couldn't have wished for a more hotly contested race at any age.
It was a very hot day in Houston, well it is summer and with temperatures soaring into the low 100s the competition was on.
There really was no upper age limit for taking part in the races, even if there wasn't a chance of winning the race they could win in their age grouping.
I think our Seniors put a lot of younger people to shame they really do have a can do attitude that I admire so much. There is a good old Kiwi saying that goes "good on ya mate".
