well you are a lot better than I am but I think i have about 20 years on you as well. Back in my prime I used to run a LOT on a regular basis although I never did it competitively. I always found the sport of cross country to be exciting but I really wanted a ball to be involved in my sports. I did run a half marathon a couple of times and that nearly killed me and you have exceeded that by far in your above example. Good job you!
Cross-country is usually exciting for the youths so, it was and is still one of my favourite sports.
I got so tired in the process but I just had to endure.
