Discussion: Training for hills in a flat area

I have my eye on the 2020 World Rogaine Champs. Highest (2665 m) to lowest (1900 m) is a lot more than local hills, which struggle to hit 20 m prominence and are more often 7 m. Assuming travel to hilly areas is limited at best, how can I best prepare?

* repeats on the small hills we do have
* weights (squats? lunges?)
* find gym with StepMill
* combination

or something I haven't considered?

Are you on Facebook?
Here’s a link to my local trail run Facebook page where someone asked about downhill training ideas for flatlanders.

This article might have some relevance. While it opens with the debate on weighted running vests, it continues into some concepts that may apply to your question.

Thank you for the perspective of framing is as an ultra type problem!

Ascending can be trained by strength training however you need to consider descending too. Consider doing repeated jumps off boxes perhaps?

Perhaps I underestimate my potential troubles, but in hills for six hour rogaines, I needed breathers on the way up but didn't suffer from going back down, unless my shoes were too small. My pace is somewhat glacial, which may be a factor in tolerable downhills?
