Higdon also covered the River to River event. One of the year's our group raced it Higdon had done a write up, I took it and edited in a couple obscure references. One referenced our #5 runner finishing downhill on section 21, emailed the writeup to the group, the #5 (one of our better runners) couldn't believe Hal had seen him flailing and frothing into the finish. Those of us on the team that were doing marathons found that many aspects of RtR were harder. The marathon was a nice 18/20 (24 if lucky) mile run followed by the second half that was hard. RtR was hard from the get go and the downhills tough especially after a previous uphill section then wait around in the van, get stiff and go again. We trained on ramps and stairs but that didn't really prep one for the downhill sections.
