Tee hee CB! Mind you, you don't say what time you ran it in - if it was 45 mins whilst its imprssive that an 8 YO has so much persistance I don't thik you need to worry. If it was 15 mins then you have a star on your hands!
Where do you live - I'm surprised there is no club. If she is really interested her school may be able to help - its xcountry season and most of them will be in the schools xcountry league.
My daughter was a runner from aged 7. I'd always run - she came home from school one day and asked if I'd take her to the local schools xcountry race at our local park the coming Sunday. I thought "OK" thinking I'd go along with her, stress the important thing was taking part and commiserate with her at the awfulness of it. She won - there were about 80 kids in her age group from all over the locality. I was gobsmacked........... it was the first time of many I cried on the finish line.
There is nothing more rewarding than sharing your passion with your daughter. My girl was very talented and over the years ran for her county and at national level. This year again she has run national qualifying time for 800m. She is 23 now and a PE teacher. She comes to stay with me in the Lakes and we spend long days out running on the fells (she runs slow to stay with me
). we often compete in the same events and we have even both won our age groups at the same events which is just brilliant!
She was very lucky in that her PE teacher at junior school became her mentor - she never lost the drive to run and she joined the local club who nurtured her talent. All her close friends were at the club so she never really got into the booze culture (though she had her moments!).
If your girl is talented it takes a huge commitment from you as well - we spent weekend after weekend driving her to events all over the country - luckily we often competed too because thats what we do, all of us including my OH and son run too. And just to see her run was brilliant. It is expensive, though my girl did win money from Europe to help her compete and her club helped as well.
The only thing i would say at such a young age is it should be fun, get her to try all sports not just running. Get her a bike - she can cycle with you while you run. Don't allow her to run on conrete - keep her on grass, sand, track. If she is destined for stardom it will come out............ then your problems really start. I hope you get as much enjoyement as we have had.
