I’m generally quite happy to let riders who are faster than me make all sorts of sub-optimal choices. Elbows out? Great! Resting on the downhill while rolling hills? Even better; rest now, pay later. But, this is a little different. First, I’ll never ride with Ted King, and even if I did, I would be so far back that it would be functionally equivalent. He’s F1, I’m doing doughnuts in the parking lot. Second, overdosing on anti-oxidants, like Vitamin C, is likely to increase your risk for developing cancer, not just hurt your response to training stimulus. So it’s a legitimate health risk to dump massive amounts into your body.
Just to be clear, I am not saying that you should avoid all anti-oxidants. Just the supplements. There is a “right” amount that’s good/essential, no one wants scurvy, but that “right” amount is easy to get from a balanced diet. Which is generally sound advice for most “should I take this supplement?” questions.
