It has been cold all week but Tom and Jay rode Friday and I joined them today.
someone was having a run today but we managed to avoid all the runners.  
Unfortunately I can't say the same for little kids on little bikes. One fellow about ten, or so, saw me passing a runner and got confused about which side of the trail he should be on. He knows now because we met head on. No body was hurt except for my big chainring which now looks like a potato chip and I will bet his bike has one heck of a scratch on it.  
We finished two laps and I split to head up the trail into that cold headwind being very careful not to shift into the big chainring.
