      Lynda,
      1st week of Breck Epic training is in the books. Went well and moved a workout to deal with life stuff. Anyways, I live at sea level and head up to Mammoth Lakes (8k-11k elevation) as much as possible for weekends. Should I take 5-10% FTP, keep changing my WKO or just manually change TSS?

      That’s some pretty substantial changes! Somewhat on the same subject. What do you believe the front of the 40+ mens field W/Kg is? I realize that there are many other factors, but for a performance goal.

        For which race are you asking about? For what duration W/Kg?

          Sorry, I was was referring to the Breck Epic and the FTP context of W/Kg.

            4.1 w/kg FTP @ 10,000 feet altitude

      Heading up to Mammoth to train is great!

      Here is a chart with the decay in power with altitude for acclimatized and non-acclimatized athletes.

      As you see you are under-estimating the impact of altitude. The benefit of being acclimatized is significant.

      At 8k your threshold will be 15.8% lower than at sea level and at 10k, 20.7% lower.

      Altitude VS Power
