Two months ago I read “Training for the Uphill Athlete” which I have found to be a real eye opener. Being into endurance training for only a few years before that I figured out that I have fell into a common pitfall of doing too much training in Z3 and above. After reading the book I switched to a regime that would (so I thought) allow me to recover overnight by training in Z1/Z2 exclusively almost every day of the week. By that change I switched from around 4 hours per week of mostly above VT1 threshold (was not able to breathe throught the nose) to around 8-10 hours of Z1/Z2 (also with more vertical gain). The goal was to build a better aerobic base in order to better tackle my first marathon in autumn. So after two months of actually enjoying the runs and also noticing an increase in my VT1 HR, I did a vertical KM run at the top of Z2. I already felt a bit nauseated at the end of the run. When I get home I usually wait until I become hungry, which usually takes around half an hour. But on this day the hunger never came which was quite unusual. I drank a big ass shake anyway because I knew I had to get around 1500 calories in after such a run. Tomorrow morning I was still nauseated and noticed that I have totally lost my appetite. Also my RHR spiked by 20%. That was on Monday. Today is Saturday and I still need to force myself in order to eat enough calories for the day (otherwise I have what I consider a “healty” appetite). I haven’t had any training sessions after the dreaded vertical km. I only do half hour to an hour family walks. RHR is back to normal though. The funny thing is that in general I don’t feel so bad. I just don’t have any appetite.
To give you a few more details:
– According to Garmin I sleep 9 hours per night on average
– I eat a balanced mediteranian diet consisting of only “whole” foods. No sugar, no junk food. The most processed food I eat is probably butter. On training days I would generally consume one extra meal after the training session.
– Currently have very little stress at home or at the office
– I think my AeT is at around 135 BPM, but most of the workouts that I did while training every day had an average HR of around 125 BPM.
– Before reading the book I did most of my runs at around 150 BPM and breathing exclusively through my mouth.
– I regulary run for 2 years. Before that I mountain biked for around 5 hours per week for about two years and even before that I did around 10-20 ski touring sessions per winter. All this sessions we’re mostly above AeT because my friends and people I usually worked out with had a better aerobic base than me. I did train Tenis for 5 years when I was younger, so this was not the first time my body was exposed to every day training.
So of course the question is if anyone can relate to my problem or if anyone has some insight on the topic? Is this possibly a simple case of “too much, too soon”? Or that I just didn’t eat enough? Or possibly both?
