I have got a new PB at ParkRun! On Saturday I did one and got 21:36. I was extremely happy and give many thanks to my great pacer.
Also, I have been doing lots of races on the track lately, in two leagues. I run for my club and I usually do 1200m (because at my age you don't usually get 1500m, I don't know why) or 800m. My best time for 1500m is 5:33, my PB for 1200m is 4:18, and my best for 800m currently stands at 2:38. I am trying to get that one down though as I am doing a lot of 800s at the moment.
Why don't you try running for a club? Sign up and join, and maybe one day you'll be old enough and good enough to run for them.
Finally, I would like to tell you about the Power of 10. It is a great website that records all of your official times that you run. Here is the link to the homepage of it: http://www.thepowerof10.info/
See you soon happy runners!
