Raced against Stadler at this years Maxdorf triathlon and was lucky not to get lapped by him! That guy is a monster on the bike.
There are few other very strong Germans in the field. Races against Taubert and Bracht (dropped out already) in Heidelberg and he lapped me there during the climb :(
Stadler, Bracht and Taubert are all the same training group and there is huge competition who is best German in Kona. If you want to do a triathlon better start in US, the fields in Germany are very deep.
