Uh-oh, look what Matt Haughey found on his family's tour of Europe: Playmobil sets for Olympic sports.
Hmm, but I can't find others. Or even this cycling one. All I see is this Playmobil Dressage horse and rider, owned by Playmobil Ann Romney.
Playmobil 5111 - German Sport Horse with Dressage Rider and Stable, $15 [amazon]
Oh, here it it: "High Performance Athletes" [playmobil.co.uk]
Horserider is not from the Olympic series, but from the girls with horses special series. Fencers and Judo competitors are great.
