New Run/Walk/Run Intervals

Jeff Galloway recently posted these r/w/r ratio recommendations for triathletes. Pretty interesting:

• 7 min/mi: run 6 min/walk 30 sec
• 7:30/mi: run 5 min/walk 30 sec
• 8 min/mi: run 4 min/walk 30 seconds
• 9 min/mi: run 4 min/walk 1 min
• 10 min/mi: run 3 min/walk 1 min
• 11 min/mi: run 2:30/walk 1 min
• 12 min/mi: run 2 min/walk 1 min
• 13 min/mi: run 1 min/walk 1 min

I used the exact recommended ratio for the 8K Crim!

I guess part of me wonders how walk breaks and ChiRunning mix. In theory, you are using much less muscle energy with a lean and midfoot strike. Still, I have a gut feeling that the two approaches might fit well together.
