Long Treadmill Workout

I did my first treadmill long run of this winter 3 weeks ago. And this morning was my 2nd - it was around 0 this morning (which is usually fine running conditions for me), but I was worried about my sore calf acting up. It got sore again last week, and I saw a (different-than-usual) chiropractor for some deep massage and adjustments. I wanted to be able to call it quits if it got too sore today, but it didn't! Yay!

Three weeks ago, I warmed up and then did some "harder" miles starting at 9.1 mph and working my way up to 10.4 mph over 6.5 miles, with my average pace being 6:11.23/mile for those harder miles. Today, I started at 9.2 mph and worked my way up similarly to 10.5 mph, so my half-mile splits looked like this:

3:15, 3:13, 3:11, 3:09, 3:07, 3:05, 3:03, 3:01, 2:59, 2:58, 2:56, 2:54, 2:51

= 39:47 (6:07.23 / mile pace)

Overall, it was 12.0 miles in in 1:20:44 (6:44 pace overall).

After finishing - the far left of the "graph" was the end of my harder miles,
and the rest was 3 miles of running easier between 7.8 and 8.4 mph.


My pace doesn't show the constant speeding up, but my heart rate does!

My calf still feels good - working on beating this pain so I can get back into regular speed sessions!
