Cuban cyclist gets nasty splinter from Pan Am velodrome

A gruesome moment from Saturday night's competition at the Milton Pan Am velodrome has many observers wondering, how is that even possible? 

Lisandra Guerra of Cuba took a hard spill during the women's cycling track sprint and somehow got stuck with a large splinter from the wooden surface.

According to Rob Good, a coach with Ontario's track cycling development program, this kind of thing is rare, but it has nothing to do with the quality of the brand new Milton facility. 

Good says when a cyclist is travelling at high speed — around 60 km/h — and they wipe out, the metal from the bike can scrape against the wood of the track, causing dangerous wood splinters to fly.
