As I posted on the C25K "quest" page, today I did a practice run on the course for my "Race for life" next Saturday. I signed up for 10k (why? why??) so I wanted to be sure I could go the distance.
I did two laps of the course where the race will be held, using the C25K+ "stamina" podcast. The first lap took 35 mins and the second lap was 40 mins. I was a bit sore to find out that the total distance I ran was 8.85k, not the full 10 - but at least now I know what to expect.
This was also my chance to try a new breathing technique. I had been having trouble with gasping for air and my nose and airways seizing up. I did a "chi running" workshop last week and the teacher recommended always breathing through the nose when running.
My gremlins thought this was very funny. "HAHA U WILL DIEEE" was the message. (Gremlins are rubbish at spelling.) I also thought this made no sense - surely you have to take in more air when you are pushing yourself? But I bought a book called "The Oxygen Advantage", which says the important thing is not the amount of air you take in but the balance between oxygen and CO2 in your body.
I tried it - and it worked! I was aware of making an effort as I ran, but I wasn't getting exhausted and running out of steam. I managed the full 35 mins of the podcast, then 10 minutes of walking, and the rest of the way I did walk-run (with more running than walking).
I'll keep practising the breathing and chi running techniques, but I feel so much more confident now I know they work!
