This is a series of puzzle caches based upon the UCI World Tour. Each puzzle builds on the next and they will get increasingly more challenging as you progress through the series. The puzzles will lead to a trail of caches along official cycle routes and therefore are best done by bike. The caches are small and will not contain swaps but could cope with a small TB or geocoin.
The Tirreno-Adriatico is a week long stage race known as the race of the two seas. The last road stage usually ends in a sprint in Porto Sant'Elpidio. Mark Cavendish has suffered at least two crashes due to mechanicals approaching the finish line of this stage. The riders race around Via Trieste and Strada Statale Adriatica.
