Congratulations on a great running week, Teresa! and you too Ayola!
Hey Teresa - nothing at all wrong with walking breaks. Have you checked out Jeff Galloway's website?
A (much faster) friend of mine who has run a few dozen marathons says one of her fastest was with a buddy who insisted on the run/walk strategy!
I took a few walk breaks today in my LR...helped me refocus when I was getting tired and sore...I wasn't any faster, but certainly felt better for it.
When I run with DH (who is only sporadic about it), we often walk one minute of every mile.
Go as long as you can, and then take another more step.
So after I ran 100 miles in 23 hours a couple of weeks ago I thought this 100k would be doable. The problem is, that 100 miles was on a flat course and this 100k was on trails, not too hilly but lots of roots and constant up and down, right and left, and total concentration on the foot plant, unlike the level track at ATY. It's a LOT more work on the legs, which accumulated and became apparent about halfway through. By the last 10 miles my legs were totally dead and it was dreadful. Plus, it was really cold and since I was moving slower I got really chilled.
Bottom line, trailrunning is generally about 1.5 times harder than road running.

PerfesserR: This is your mom talking: Make notes as you go along from now on, such as: "X amount of recovery time after a 100-miler" and "no ultras within 2 weeks of each other." You're not SuperMan after all; but you are an Extraordinary Ultrarunner! I'm glad you got it done, but don't do that again. Got it? Now take some time to recover. I care and want you to be able to keep doing what you love with a sound mind and body.
