I love that stuff, but now I'm depressed. I timed a 1:31 lap using the entry into the 180 as the mark. First lap in was 1:14 at that point then 2:45 the second time. If my math is right, that's a 1:31 lap!
For the depressed part, my best to date is a 1:44 ugh, gonna be tough to squeeze another 13 seconds out!
