Ran the RnR Arizona Marathon this past weekend in 3:43:14, a PR by  6:10.  But, bonked in the last couple of miles with some severe cramping  that dropped me to a hobble and near crawl.  Se la vi, still got a nice  PR and an awesome weekend in the sun with my wife, so I'm happy. 
The  bonk is purely my own fault.  I completely forgot to bring my  Endurolite capsules from the hotel, and the Cytomax that Competitor uses  makes me sick, so I couldn't drink that.  I fueled with a multi-hour  bottle of Sustained Energy, water along the course, and planned on using the salt  capsules, so going without any electrolytes was one of my downfalls.  I  also went out too fast.  I put the hammer down early in the race when  everything was feeling good and decided to go for broke, which was  probably a mistake given I was cruising without any added salts. Oops.   And I likely put too much into my training.  I ran a 3:49 in Chicago,  and signed up for this race as redemption.  It was too soon, and I  really pushed my limits in the 13 weeks in between.  Got a PR for weekly  mileage at 67, and just shy of 300 miles in December, but probably put  too much effort into the training which left me depleted and worn down  on race day.  Plus, I tend to race too much anyhow (yeah, my singlet  gives it away), my own fault. 
Splits were awesome up until mile  20 though.  Then my quads starting cramping (the course is a little too flat  IMO), and by mile 24, had dropped to a run/walk shuffle.  10k, 51:22,  8:16 pace. 13.1m, 1:46:25, 8:07 pace.  20m, 2:44:26, 8:13 pace.  26.2,  3:43:14, 8:31 pace. 1:46:25/1:56:49 first/second half splits. 
I'll still take it though!
