52:32 I actually kind of pushed it a little at the end...wanted to beat my time yesterday. I wouldn't really overdo. Mostly I just listen for signs of distress in the general stomach area and if things feel okay there I'm good to go...and if I don't really feel like I'm working too hard. I obviously won't be doing any tempo runs but it was okay to play a mild game of beat the clock. Joseph has decided he's a baby again this morning...after three great days of potty training he thinks he needs a break. |
