5:48 is a fine time, especially since the marathon was tougher than you had expected. So many factors come into play, how well you slept, how your shoes fit, how much water you drink, the uphills. You now have the memories, stories, a finisher’s medal and most likely a few blisters.

Congratulations! Running a marathon is a huge accomplishment. Be proud of yourself for setting the goal and following through. You are now a different person than you were yesterday. :)

Cheers!
