I think Hermes nailed it, too.

Medications? No, except for a "post menopausal" med I'm taking. My heart is healthy, and I have no BP issues what so ever.

My performance, as in endurance and reserves, has shown an increase in the past month. However, that seems more tied to weight gain and protein intake than anything else. In other words, if I eat right, I'm strong - umm, duh?

As for overall gains, I have not noticed anything substantial. I can run farther, but I still climb slowly on the bike. That's really all!

The Tierra Bella will be fun, I'm looking forward to it - thanks!
