I dont think she'd be there if she wasnt, the race was always mentioned as part of her seasons goals, not just something to do before the Olympics and instead of Tdff
At the same time, in order to be peak form for the Olympics since she will be doing the omnium and the madison as well, at least in theory she probably will have had to sacrifice some of her climbing form. Even Geraint Thomas, the poster boy for bulky trackies deciding when well established road riders to suddenly be an elite climber, had to sacrifice stage race ability at the altar of track medals in 2012.
And at last year's tour, despite everything, she still lost 3 and a half minutes on Tourmalet which was the only proper mountain stage (although of those that beat her that day, only Juliette Labous is in attendance here) - and that stage was not as difficult as the Blockhaus stage here (Aspin 12km @ 6% + Tourmalet 17km @ 7% as against Lanciano 11km @ 8,6% + Blockhaus 16km @ 8%) as well as the rest of the route having significantly more climbing than last year's Tour. Now, Lotte did win on Jebel Hafeet in the UAE Tour, but that was a Unipuerto stage with 10km @ 7% - a pretty solid climb but mostly a very consistent one, having been built at a relatively modern time with much more up to date equipment and better for tempo riding. She did beat Longo Borghini and Realini, which is a marker even for a February race, but that race also did not feature climbers like Labous, Uttrup, Santestebán, Chabbey, Magnaldi or Lippert (albeit Liane's form will be a complete unknown here as she hasn't raced much this season due to injuries), plus of course in February you can never be sure what others' form will be like.
If Kopecky
does have designs on the GC here, she probably needs to grind a few people to dust in the tempo MTF on stage 2, and maximise her time gains in the first half of the race, but if she's losing 25 seconds already on stage 1 then I suspect she won't fight for GC unless the opportunity presents itself, such as she finds herself in the right breakaway, or she attacks for a stage and the bunch dithers behind and lets her gap become decisive enough that she re-enters the mix.
