I always concentrate on my breathing during a run as it helps me get into a rhythm and focused on being in the moment. If you are having problems then you might like try these tips.
Firstly, try out different combinations of breaths in and out. I find in for 2 and out for 2 works for me. You might try 3/3, 2/3, 3/2, 4/4 etc. Experimenting with different combinations to see which works best.
Secondly, being tense in the shoulders can prevent you from breathing in properly. Relaxing the shoulders by pushing them down (rather than being up around your ears) allows for taking a deeper breath.
I saw an interview with one of the councillors on the tv this morning. His argument that they charge £60 for football pitches so parkrun should pay something as well is nonesense. When I ran a football club we would expect nothing less than: well cared for grass; lines painted; goalposts; nets (without holes in them); changing rooms; toilets; showers (with hot water) and suitable parking.
What would the parkrun expect for a levy of £200 per week?
Whatever the parish council decide to do its bad publicity for them. Although parkrun is free for runners many locations must do well out of parking charges. I reckon the council must make £60,000+ a year from parkrunners at my usual run. An additional levy would certainly stop me from going regularly.
