I've been reading a book by Julian Goater "The Art of Running Faster". It's a very well written book with some good advice. I joined some running club friends for a "Cup Cake Run" yesterday (yes, it ended up in a tea shop with a wide choice of cup cakes !) and we covered about 6 miles.
I tried some of the advice in the book - one was just slightly changing my gait , he says to keep your hips and chest forward, feet under your body, not reaching forwards and that you should feel as if you'd topple forwards if you didn't move your feet. It's hard to describe - it wasn't a huge change and it felt as if I was closer to a mid-strike than a heel-strike. It didn't make me hugely faster but I felt as it would be easier to work on speeding up.
I also tried his technique for running up hills - same cadence but shorter steps. That seemed to work very well - a couple of friends commented that I was racing up the hills ! I was still having short walk breaks, as I have done during my past couple of months of health problems/low blood iron/extreme tiredness, but I felt stronger and I tried two or three sprints as well. I suppose I was doing my version of fartlek training at times. I enjoyed it so I'll try and do it more often.
Julian Goater also says to let your arms drive your legs - since being told my shoulders looked too tense, I've been concentrating on keeping them relaxed so yesterday I was trying to use my arms to drive myself forward while still keeping relaxed. It seemed to work !
My legs felt tired towards the end but after a short rest I felt as if I could set off again - but a had a pot of Earl Grey instead !
The book also suggests running twice in a day if you're wanting to increase mileage - it's easier to fit in and still gives you time for rest days. I'm thinking of heading for the gym & the treadmill on Tuesday & Thursday mornings, maybe to try the C25k+ podcasts or just 30 minutes of intervals, then going to running club in the evenings. Then one longer run at the weekend. Am I mad ?
