The disqualification rules are pretty ridiculous sometimes. Just now a Brazilian runner Rosengela Santos competing in a women's 200m round got to the 'on your mark, set' point and she sort of fell forward from the block.
It was obvious she didn't try to jump the gun, it was a slip. So they disqualified her and restarted the other women. Why don't they use some discretion! I think it's bad enough that they disqualify anyone for jumping the gun just once, but disqualifying someone for an accidental mistake who has trained hard for months is way too harsh.
Eilidh Doyle comes 8th out of 8 in the 400m hurdles final. I know she's got some medals but we really need better athletes than her.
