    Hello 80/20 Community,
    I am currently in the eleventh week of the fifteen week half marathon level two training plan. The first ten weeks went incredibly well. I felt mild soreness at times, but never so sore that it was painful or cumbersome to run and execute the workout as planned. However, my past three runs went poorly, particularly my half marathon pace workout, which was much slower than planned, as I felt physically unable to run at the planned pace.
    One theory I have is that the soreness is the response of my body to an abrupt change of the terrain on which I run. I was used to running on flat Chicago terrain up until a week ago, at which point I moved to Minnesota, where I run on rolling terrain.
    I am trying to keep my spirits up but it is demoralizing to have ten weeks of good training just to have it fall apart when I am two-thirds of the way through my plan, especially when it is due to general soreness, rather than a specific injury.
    Has anyone in the community experienced anything similar, or have advice for me? I would appreciate any thoughts or advice offered.

    Your hunch seems highly plausible to me. If you have access to a treadmill, I suggest you try doing every other run on it and see if that helps. If you don’t have treadmill access, try to find a flat outdoor route to run on a few times per week, even if it means doing multiple laps on a short loop that avoids hills. You will adapt to running on hilly routes, but these measures will help ease the transitions.


    Thanks, Matt. I will certainly try that, as I have access to both a treadmill and a track.
