It wasn't 100% walking it was walk run but at 14-15mm pace I might as well have walked
My normal running pace when fit is about 12-12:30mm and 180
I have a garmin
I've only run "fast" once which was a 1m race at 8:55 maxed at 198 then,
did 201 in a tempo run later that same month (2008 when I was really fit, running daily to forget my grandma had cancer), 202 interval training in the July, 200 in a 10K race in the July
can't find the 205 but it was on a tready doing a MHR test, saw 203 in a 5m XC race going up a very steep hill
Never once have I got to the puke stage so it must be higher
