Saturday run

Today's run was either suppose to be 35 minutes or 40 minutes.  Last weeks LSD run was suppose to be 35 minutes (but I  pre-rode the bike race course instead).   I decided on the 40 minute run because I seem to do better on longer distances.  The run started out difficult.  It takes a good 15-20 minutes for me to warm up.  Once I was warmed up, I felt really good.  494 calories; 40 minute run 137  (69%) average heart rate; 156 (78%) maximum heart rate.  One lap of lake was 27 minutes.  Second half of run was at a higher heart rate.  5 minute warm up and 17 minute cool down.
