trail legs

[Jim Adams]

the first signs that you are starting to get your trail legs is that you will still run out of breath but you'll notice that your steps are getting longer and you're going further between stops.

After two weeks, I tend to really hit my stride. I did the same amount of miles per day at the end as I did in the beginning. It just got easier.

Shoes,
What kind of aerobic conditioning are you doing?
You said you are up to 3 miles on a bike?
That's not really a lot. Are you overweight?
I tend to slow down if I get out of breath but keep going. If I stop once I tend to keep stopping on a long climb-it seems to get easier to stop.
