Hi Patrick
You mentioned that you're new to endurance riding. I was in the same boat last year - and ignored everybody's advice to increase my effort prudently (I stupidly rode about 11,000 miles total). I'm paying the piper this year for not heeding that advice- this year has been a struggle and I'm kicking myself for what I did last year.
As I understand overtraining - it's not so much about being uncomfortable (after all, aren't cyclists 'supposed' to suffer? : ). Over training leads to a failure in your ability to maintain or improve your effort. In severe cases it could be months (or even years) to recover- to have the capacity to increase endurance and strength.. So I suppose prevention is a good idea (I work in a sports medicine environment so appologies if below sounds a bit pedantic...).
Most discussions about over training relate to acute symptoms - soreness, mood changes, fatigue, drop in power, change in sleep patterns, etc. All are true and are worth notice. However, there are other physiological markers (esp cardiovascular, endocrine and inflamatory) that dont generally make the list. All of them could have bigger effects in your over all health. The significance of these factors depends on your age and history (as well as genetics and general health). If you have been exercising consistently and at a high level all your life, then you may find that adapting to and maintaining a large volume of exercise may not be a problem for you. If you are like many of us - a little long in the tooth and have spent significant numbers of our earlier years with beers on the couch -it's always a good idea for you (and your doctor) to know and understand your
numbers. For example I had a tough time convincing my doctor that I wasn't an alcoholic- my serum protein and albumen levels were in the basement and liver function enzymes were high. Turns out that excessive execise can do that to you and can scuttle your capacity to recover. You may feel fine and you're riding well but you've got new persistant elevations or depression in blood pressure. Time to dial to back and take better care of yourself.
Pay attention to your symptoms after rides and especially pay attention to changes in those symptoms. For example, if you notice that you're puffy in your extremeties during/after a ride, do the symptoms appear earlier and last longer? If so dial it back. And get really adept at attending to your recovery needs- and that isn't just limited to high quality nutrition post ride. Most of the high-level atheletes i know are pretty religious about regular active recovery (for you, that would be a couple of hrs of soft pedaling w/ a heart rate < 120 bpm). There are several studies that connect chronic sub recovery in endurance atheletes to negative cardiovascular changes- stiffening and leaky blood vessels, cardiac arrhythmias, persistant elevation/depressionof blood pressure etc. I suspect that a lot of us ride our seasons in this state. A study of healthy young men showed
that it takes about 30 days for the cardiac ejection fraction (a measure of heart output) to return to normal after running a marathon. Your mileage may vary.
And finally don't get greedy. Don't ride big rides so often that your body doesn't have the time to fully recover between rides. Your goal shoult be to get stronger over time. You may suceeed in dragging your body through lots of rides this year only to discover that next year all your wheels have gone flat.
Happy riding!
