But see, Eric, we got the infomercial foot. An arch is great for stability 
while standing, but we also need to run across the savanna to persistence 
hunt our Kudu. Our foot is not just an arch, but an arch that becomes a 
windlass mechanism for storing and returning energy. Grin. I'm not sure how 
the physics of that work on a bike pedal, but the experience of riding most 
of the time for me is very close to the experience of running, not weight 
lifting. Weight lifting kicks in only for the steep climbs.

With abandon,
Patrick
