10.2 on the Landice

Ran 10.2 miles on the Landice, 1:18:02, 7:39 average pace (7:19 incline adjusted); middle 8.2 in 1:01:15, 7:28 average pace (7:11 incline adjusted). First 7-8 okay, last two tough, really really wanted to just stop. Progression, 8:25 pace down to 6:45.

Pretty sure the 2% incline I'm running (3% for first/last) is steeper than at the club, putting a level to the floor does show a slight uphill. 86 year old house, no level surfaces or right angles in sight. A little obsessive, but I wonder if there's an easy way to measure the actual incline percentage.
