British sprinter Dina Asher-Smith is getting ready to compete in her first Olympic Games (kicking off on 5 August).
But before she heads to Rio she's running by the ELLE offices to host our Wednesday Workout.
After a tour of the #ELLEFASHIONCUPBOARD, the 200m European Champion and fastest woman in British history will give the ELLE team a run for their money out on the streets of London.
We're looking forward to hearing how Dina's preparing for the Olympics and what she'll do when she wins a medal in Rio (because we're sure she will).
But most of all, we're looking forward to finding out just how fast you have to be to keep up with the fastest woman in British history.
If all else fails, we'll run in her slipstream all the way through Soho.
Tune into ELLE's Facebook page on Wednesday lunchtime to see all the action.
