at altitude

While on spring break, we're still in training for the Cleveland 10K in May.  I skipped a few workouts last week because I had this chest cold.  Well, I still have the chest cold, but I can't totally stop training ~ and my training partner is kicking butt.  Since it's my "goal" to beat him ~ I've been running in the Rockies.
Sunday I struggled around the development.  It's a mile figure-eight loop and half in downhill while the other is uphill.  And let's not forget that this is at 9,000 feet.  I managed to get one and half miles done.  Monday we went for a little flatter course and ran three miles though the town of Dillon.  Today we woke up to four or so inches of snow.  (Yeah spring break)  Mike was bold (and wanted very much so to test out his new Garmon Forrunner) and he went 6 miles along the bike path.  I chickened out going with him because it was still snowing and blowing and my chest cold is putting me below 80%.  So I just ran the development.  I managed to get three miles in and it was good.  Hills are hard and hills at altitude are harder.  I'm hoping it will be easy running we we get back to 300 feet.
