My dad ran the London marathon 4 times, and various other marathons too. Loads of the runners (male and female) just wee where they are, especially at the start where there are thousands of people waiting together. Yuk! Must smell bad. Never asked about the other!!!
Many athletes and sports stars have very strict diets and pre/post activity routnines. It sis not abnormal. It is what they have to do in order to be the best, pr at the top, of their game. It's dedication, that's all. Ice is for the muscles - to try to avoid damage to them afterwards. And vaselines helps witht he chafing - men rub in all around their bits to help with chafing there , and most runnrs round their nipples where the vests rub. Worst thing is though - the runners tend to share one big tub between tem - urgh!
PR has not come form nowhere; she has been a runner, IIRC, for many many years.
Think it is sad if she has had fertility problems; many female sports stars do duffer from this - one of the problems witht he job - and they often cannot come back, to the same high form, afterwards.
Missed most of the marathon this year. Will ctach up later.
