Still a noobie here, so I'm going through the same old voyage of discovery that all new runners go through! The latest bit of research concerns cadence and trying to decide whether I need to try to change it in some way.
I'm sure I don't overstride as I'm a midfoot/front foot striker, slow jogs are 160 cadence, 21k super slow was 7:00 pace at 160, faster 30 min 5k is 165, 1 hr 10k at 6:30 is 165, 26 min 5k is 170, fast 0.5 km at 3:00 is 190. I've not run any distance around the magic 180 mark yet (yes I know this 180 holy grail number is hot potato) so I plan go do a 180 slow run/jog today to see what that cadence feels like. I've got some minimalist Merrel Road Glove (minimal drop) shoes that I'll wear to help simulate a more barefoot style shorter stride (I bought them by mistake a couple if years ago in a sale not knowing a damn thing about what type of shoe they were and have used them for playing badminton up till now!)
Have any of you messed about with a focus on cadence? Have you managed to modify it to the benefit of efficiency, speed, endurance?
