Like the OP, I will have 45 mile hike to get home it at work when TSHF. My GHB isn't as robust as the one listed. I need to keep it light enough that it doesn't slow me down. I walk a sustained pace of 4 miles per hour. I'm tall, I have a long stride. I've upped the 120 steps per minute to 135 - 140 steps per minute. I've done road marches and I've done the 100 mile Nijmegen March several times. With a walk as far as mine or the OP, I suggest looking at a map and giving yourself a Plan A and a Plan B route. Don't forget to put railroad tracks in the mix. This often cuts into the distance.
Originally, my GHB included a set of BDU's but I've since changed that. I don't want to appear to be well equipped on the trip home. I want to just be another person trying to make my way home. I have to go from Jonesboro, GA to Monroe, GA. I plan to make it home within 24 hour period. At 3 mph, I'm looking at 15 hours. I have an office in Conyers, GA which is the perfect place to get rested up and replenish water and food as it sets just over 1/2 way into the trip.
Of course, I do not have to worry about dealing with snow.
