My kids learn about animal habitats in school - desert, forest, water, underground, polar, etc. They know about one other one too - the triathlete habitat. They can recognize the identifying features - can you? What are we missing?
Here are some of the clues:
large collections of running caps and swimsuits
unusual items plugged into a computer like AquaSphere goggles (iPod affixed)
hoarded nut butters and special powders
rolling devices of all sizes and shapes, magic healing gels, special water bottles
bike as furniture
large random numbers, found hung together in no obvious order
running shoes. and more running shoes.
wheels in odd locations
