Garanichev also did Canmore but skipped Presque Isle, so is planning to prepare for the Worlds by that route.
The European Championships are traditionally a sort of halfway house between the IBU Cup level and the World Championships - a lot of the second tier nations and smaller teams who don't expect to have a shot at winning anything at the Worlds will send their best athletes to the European championships to try to get medals and to prepare for the World Championships as well, we've seen medals for the likes of Andrejs Rastorgujevs there before in recent years. What you typically get is the IBU Cup level athletes for the biggest nations, juniors holding form from their own Worlds, and the main teams from countries like Bulgaria, Romania, Estonia, sometimes even the likes of Poland and Slovakia. You'll see established World Cup names on tomorrow's start lists, as well as Garanichev there are others like Jaroslav Soukup, Eva Tofalvi, Krasimir Anev, Michael Rösch, Matej Kazar, Jana Gereková, Henrik L'Abée-Lund, Daniel Mesotitsch, Nadezhda Skardino and Vladimir Iliev, yet the biggest nations' teams are either young prospects (Norway's women) or previously established World Cup names who've fallen down in the pecking order and could now be classed as reclamation projects (Florian Graf or Svetlana Sleptsova, for example). Quite often the host nation will include some bigger names than you might expect. Last year Ekaterina Yurlova competed as one such reclamation project following a poor previous season, which is what got her the start in the World Championships Individual she surprisingly won, and I think one of the main Polish women, maybe Nowakowska, won a few medals as well.
This year the competitions being in Tyumen' has affected the field somewhat as it's still a fairly significant distance to travel.
