AM: Stairmaster 4.43mi. Level 6 (45 mins.;10:09min./mi.) 2120’ followed by 3x1min. sprints (4min. recovery)

So someone at work was using the treadmill, so I decided to hit up the stairmaster (it's been a couple/few weeks).  I stepped level 6 Pikes Peak for 45 mins.  It ended up being 4.43 miles with 2120' ascent. I then hit the treadmill up for some 1 min. uphill sprints (12% incline).  I ran them at 8.6mph(6:58min./mi.), 8mph(7:30min./mi.), and 7.5mph(8min./mi.) with 4 min. recovery rest.  C-D: BF 1 mi.  TOTAL: 5.6 mi.
