Interestingly, Wikipedia has the following to say about 222
Which only goes to prove that mathematicians don't get out much. Unlike me, as I did Week 2, Day 2 of the couch to 5k programme after work tonight. Stats here. Made a good start and starting to feel the stamina building, but still got tired by about half way - which is evident in the pace graph.It is a decimal repdigit[1] and a strobogrammatic number (meaning that it looks the same turned upside down on a calculator display).[2] It is one of the numbers whose digit sum in decimal is the same as it is in binary.[3]222 is a noncototient, meaning that it cannot be written in the form n − φ(n) where φ is Euler's totient function counting the number of values that are smaller than n and relatively prime to it.[4]There are exactly 222 distinct ways of assigning a meet and join operation to a set of ten unlabeled elements in order to give them the structure of a lattice,[5] and exactly 222 different six-edge polysticks.[6]
After the 5th and 6th running sessions I was totally out of breath, so have done a bit of research on breathing techniques. Apparently I am a 'belly breather' and that is a good thing! You chest breathers have got it all wrong. Going to try the breath in for 3 steps / breath out for 3 steps on Wednesday. Not the best method as this rhythm always starts on the same foot. The more advanced technique requires breathing over a a total of steps which is odd (3 in 3 out = 6 steps = even, so maybe 3 in 2 out, giving a total of 5, which is odd, meaning you start the breath in on a different foot each time, which is better for spreading the stress)
Think I'll try the 3/3 first and do a bit more research before trying the 'odd step' method.
