It's also worth taking into account that she's running Chicago - which is notorious for having it's GPS splits on runners watches all over the place in the first couple of miles because there are so many skyscrapers. No watch will be able to overcome that, and would be interesting how she'll cope given she has zero resiliency, ironically. Maybe have another 'panic attack' like the one she claims to have had a few weeks ago (which clearly was not a panic attack!) and was apparently caused by her Garmin.
