Is This A Sign?

My short daily runs have been going well.  My legs have stayed pain-free and I am picking up a little pace (that'a a relative term).  All in all, I'm happy with my progress.  There has been very little biking over the last few months, so my speed and endurance has suffered (memo to self:  Ride More!).

I've been invited on  a 40 miler on the Suncoast Trail this morning.  I have to admit, 40 miles is sounding like a long way for me today.  Never the less, I'm up at 5:30 gathering supplies and filling water bottles.  Then, out to the garage to get tire pressures adjusted before heading out.  Front tire - 120 psi, no problem.  Back tire - 20 psi and I hear a hissing noise.  Seems to be coming from the valve area.  Take hose off, re-attach, pump, hiss, repeat.  After getting frustrated with my pump, it finally dawns on me that the pump is fine - it's the tube.  5:50 a.m. - glad I have spares, time to change it out.  Funny how your mind doesn't process things clearly before 6:00a.m.

So, I'm sweaty and writing.  Wondering if the flat is a sign that I should cool off and go back to bed?  No, I'm going with the idea that the worst of my ride is behind me and that I won't get dropped.

I'll let you know how it goes!
