Some students would have to start at 600 meters with led shoes and weights in their hands. And another group should get to start at 200 meters on bikes.
when I read 'led shoes', I thought of the one that literally have LED on them and flash/glow. Then I realized it was meant to be the lead element (Pb), that's actually pronounced (led)...
Also typing/pronouncing/using 'LED lights' makes for a great tautology. ("Light emitting diode" lights)
