As for the woman, it's inconceivable she thought she could get away with it - it's easy to spot, with magnets if nothing else. Possible it was a trainer that got mixed in, or someone else's bike, I think they're claiming. Possible.

I'll let them decide, but it would quite stupid if so if they brought it to race day.
