cross that bridge when you come to it

I was running on the Main river in Frankfurt and was trying to think of an alternative to running one side or the other, or up one side and back on the other, and discovered a topological problem.  What if I ran down one side of the river, crossed the next bridge I came to, continued down the other side to cross the next bridge, and just continued doing that?  Eventually of course I should cross a bridge and head back, but continue to cross each bridge when I come to it on my way home.  I was thinking it through and discovered that as I crossed a bridge on the 'out' and 'back' part of the run I always crossed any given bridge running the same way each time.  I first thought this depended on whether there were an odd or even number of bridges, but I was jogging along trying to mentally draw these paths out and couldn't find a way to "cross each bridge when you come to it" and cross each bridge both ways.

my Garmins view of this run

I won't bother with you my observations on the first and last bridges crossed ...

p.s.  After getting home, I found these kinds of problems have gotten plenty of attention - see for example Seven Bridges of Königsberg

Scott Jurek - Appalachian Trail day 22

I took a chance on finding Scott Jurek on his AT trail adventure today, and had the best of luck.  I parked in Washington Monument State Park, and after a quick trip to the top of the monument for a look-around I got on the Appalachian trail heading south.  I passed the South Mountain Inn (which marks the top of the Alt-40 hill climb at the start of the JFK 50 Miler) and continued south down the trail.  In less than an hour, I ran into him running down the hill from that antenna farm at the top of the hill.


Scott seems to genuinely enjoy people coming out to run with him - although I have to wonder if he's not losing some real time over the period of his record attempt giving time for selfie photos with fans!  I heard several people ask about what he was missing, and he seemed to be craving Thai food and vegan ice cream (never had that ...).  And any vegan deserts - but nobody had any of that.  There are lots of pictures of Scott running - but here is one of him eating (it is eat and run after all)



Scott has great supporters in his wife and ultra community.  I met Karl Meltzer during his AT attempt last year and saw him momentarily again in Washington Monument Park today,  And I wasted some of his time with a selfie (thank you Speedgoat!).  I didn't get one with Scott - that's  30 seconds saved.


If you bring nice gear out on the trail, it can get a bit trail-worn before you know it.  If it's really good gear though, that's OK.  Scott has taken a couple of weeks of hard wear on the trail.  I think I heard him say this is the hardest thing he'e ever done.  But I was impressed with how well he's moving and how strong he's climbing.

Good luck Scott!
