As my last block of training before heading into full blown race season, I had planned a training camp at altitude but I wanted to do it at home, in Victoria. Following the "sleep high, train low" philosophy, I decided to sleep at about 6000 feet while continuing to follow my VERY demanding training schedule without modification. This can be facilitated by using an altitude tent by Hypoxico. This year I have pushed to new levels not only cycling but definitely with my swimming and running, but using altitude can improve your aerobic fitness quicker and with less damage on your body because it will challenge your cardiovascular physiology without impact/training. There is a lot of debate over the effectiveness of altitude but I find it is mostly scientists that are debating whether it works. Coaches and athletes are just doing it and winning and not worrying about debates over scientific evidence. I truly believe that altitude, whether it is real altitude training or in a tent, works well for developing endurance fitness.
However, altitude is very demanding. There were some very ugly days in the pool, on the bike and trudging through some runs because altitude adds another heavy load to your body beyond what you are treating it to while training. Because I was still training at sea level, I could still do all of the quality work that I had planned, which really isn't possible when you go to altitude to train (at least until you are acclimated). It is important to use every physiological marker you can to determine how your body is recovering: your morning heart rate, your weight, an evaluation of how you are feeling and, particularly while training with altitude, your blood saturation (as determined with an oximeter). While training at altitude I use an oxygen monitor to determine exactly what % oxygen is inside the tent and an oximeter to see how this % oxygen is affecting me. HOWEVER, if one of these markers should be inaccurate, say due to an oximeter that is a piece of junk, you may make unfortunate decisions based on the marker. One of these poor decisions might be increasing the altitude. And thus begins the story as to why I skipped the NORBA in Fontana….. Read more
