Ran a half marathon this morning. It was more than twice the distance of the longest race I had previously run. I ran it in about 2:17, not exactly blistering time, but I was happy to finish and now am looking forward to doing another.
Congrats! Anytime you push yourself to a new challenge, you should be proud of your accomplishment (right now I couldn't walk a half marathon in 2 days and 17 hours, let alone 2:17!)
