Interim Report
Before I post my race report for the Douro Valley Half Marathon, I want to post more information about the Madeira Island 25K Trail Race that we ran the weekend before the half. I have now been able to analyze the run on my Garmin, which explains a lot about why that race was so painful.
Now that I think about it, if you start your race at 3300 feet and run down to sea level but you have a net elevation gain of 3500 feet, then that means you have a net elevation loss of 6800 feet. I see. That’s why everything still hurts.
