Try running 10 miles in it.
I swear, you would think that it never got above 50 degrees in Maine in the summer by listening to people's conversations today. The line in front of Gifford's ice cream shop (some great ice cream, made right here in Skowhegan, Maine) had at least 10 people standing in line all day.
But little old me, with a hurt hip all week, rose at 5am to drive to Bucksport to run my 2nd Tour de Lac, the 3rd oldest road race in the state. I prepared for the race by overdosing on Motrin and rubbing 5 layers of Icy-Hot on said hip. Luckily there were 5 water stops along the course since I took one gulp at each and dumped the rest right on my head. I almost quit at mile 3, but found my groove and then started slowing down around mile 6, but the last 2 miles I was dragging. Final time: 1:19:31, a 7:58/mile pace. I have never been so glad to finish a race, but the best part was that the outdoor pool opened up early just for us and we could swim in our race clothes (I brought a change of clothes, but no bathing suit) before the awards were announced. The cool water just sucked every degree of heat right out of my muscles, it was just lovely. I won a jar of homemade blackberry jelly for winning my age bracket.
