WHO HAS ALL THE ROUTES IN THE POKEWALKER?
 

I almost have all of them but i need about 5 more! :D

I have most of them, including all of the event ones up to date. I might need 5 more.

do you know if there is any more events?

I think I have all but five of the unlockable ones, plus Yellow Forest and Winner's Path.
There are three more event routes which might be distributed: Rally, Amity Meadow, and Sightseeing, unless these have been distributed and I haven't heard about it.

I have many of the unlockable routes (I think the most recent was Sinnoh Field) and all of the event routes. I haven't used my Pokéwalker in a while, though...

I do, but I stopped using it. Mainly because I keep forgetting to pick it up before I leave the house.

I have all of the pre-National Pokédex ones, and all of the currently released event ones.

I don't have that many I will unlock a few after I beat the 8th Gym Leader
