Training & Nutrition - Training with adrenalin?

I think most would agree that you can ride much harder when you're in a competitive situation such as a race or a tough group training ride. Infact, I've observed such a discrepancy with myself that I'm wondering if it's worth training on my own at all. After a race my legs are much more sore, and sometimes I get that feeling my chest like I'm gonna pewk. I never experience these effects after riding alone.

Anyway, I'd like to know if anyone has some science on the effects of training with or without adrenalin.

Would it be more beneficial to do most of my training in an adrenalin-fueled situation?

It would be worth riding on your own and posibly run into to someone that will challenge your fitness, that's what I do when I ride on my own. And if you don't run into anyone then this would be a good time to find your self-motivation to ride harder on your own. I think being able to push yourself will also help you improve your riding pace.

No science here but...

I do most of my hard training solo. I know for a fact that my hard race efforts regularly exceed what I do in training. Is this bad or is it holding me back? I think the answer is no.

The problem with race level efforts is the amount of time it takes to recover. If your training efforts are always at 100% of race pace/effort, you cannot recover fully in time for your next workout (at least I can't). The true trick to training, and why most top level cyclists have coaches, is to figure out how hard you can train yet recover fully and still peak for specific events.

PS - I've felt like vomiting after 2x20 intervals on a pretty regular basis.

Thanks.

I probably should've asked: "do you achieve a superior training effect from riding at race pace with all that adrenalin?"
