This Saturday's LSD was 10 miles, the plan is to build that up to 24 miles over the next few months. The other learning aspect of doing the longer distances, you figure out what works for you in regards to eating & drinking while doing this. Currently I tend to 'fuel' my longer distances with Gummi Bears, Granola Bars, water, and orange Gatorade. I'm sure I'll experiment with different foods & drinks to see what works best.
I am told and have read that the LSD is the key to being able to do the marathon. They do emphasize that one should actually go slow (slower than race pace) on these. So, with my goal of walking the entire marathon (26.2 miles) under 6 hours, that would mean my average pace during the race will need to be less than 13:43 minutes per mile.

Actually I'm shooting for a 13:00 minute/mile race pace, so that means my LSD speed would be ~2:00 per mile slower, 15:00 minute miles or roughly 4 MPH.
