I enjoy your writings and find quite abit of usefully or extremely interesting points in almost ever posts.
Even though I know the answer is monetary. It seems a waste to have all the top Kenyan women only run 1/2 marathons and marathons. There are enough women in the last 10 years that proven you can be top elite marathoner and still balance some outstanding 10000m championship races in your career.
Women like Mary Keitany that just went thru 10km in under 31 minutes and continued on for another 7 miles but her 10000m track personal is a high 32 minutes is ridiculous. Renato it seems that with her current fitness and some track training she should easily be capable of going under 30:10 on the track or slightly faster. Kenya lose most of it's top 10000m talent to the marathon; however, in Ethiopia the 10000m seems to be slightly more popular then the marathon for it's athletes.
There's no money in the 10000m. The half marathon and marathon lists will get deeper and deeper in the coming years. Rosa said it best: a former world champion can run 13:00 in Oslo for $200 (before taxes and paying his agent) while a guy you've never heard of can win $20,000 running 2:09 at the Dublin Marathon. Where would you put your talents?
