Professional cyclists aren’t to be messed with.  Just ask a fan who tripped up a cyclist during a big race this weekend. 

The fan took a big time slap to the face after interrupting the race.

Via TMZ Sports:

It all went down during the Giro d’Italia race in Italy on Saturday … when a spectator who was running alongside riders tripped up and accidentally knocked into Miguel Ángel López‘s bike.

The Colombian cyclist was thrown from his ride … and in response — he went OFF on the fan!!!

Who knew there was so much power in the hands of guys wearing those silly cyclist outfits. 

No wonder they ride in the middle of the road on the weekends.  They aren’t afraid to throw down.
