I finished my first-ever Ragnar Relay Race around the Big Island of Hawaii, 15 miles total in the span of about 26 hours - triple the distance of any previous run I have done in quite some time. There were ten members on my relay team, and each had their own remarkable story of overcoming adversity.
Surprisingly, my muscles feel pretty good, no blisters or injuries, but did come home with a nasty chest cold. Nevertheless, it was worth every minute!
You get out of life what you put into it. Try moving outside your comfort zone, and go have an adventure!
