Yawning

Hi all

me and one of my rants again........

so yesterday my fantastic wife said to me time to go get you some better shoes to use as I had been telling her how some days I was getting a burning sensation in my feet and my ankles hurt

as it happens I missed all exercise yesterday as I had a 7am meeting at the office - 1hour from home so I skipped my morning walk, after work picked up the wife and off to Harbour town - picked up a pair of Mizuno Wave Inspire 7's and back home for 10pm

heres the strange thing - woke up at 6 and off for my morning walk - well the first 2kms were hell feet felt wierd and I could not stop yawning no idea why that was and am open to some advice - I use endomondo and this shouts out every time I pass a Km mark - I then get told in my headset what my time to complete the last km is and I was fully 1minute slower than usual.

now was it the shoes or something else - methinks something else as i then started to pick up the pace and for the rest of the walk I upped my mace to around the 9min 30sec mark/km (6kmh which is around 3.75mph)

however i could not stop the yawning first time I have ever had this happen to me - yeserday I went slightly over my target daily useage but cannot see what I did to cause the yawns, shoes stopped feeling weird and settled down in fact at the end mark I had no burning from my soles and much milder ankle pains - im presuming some of the ankle pain is due to my obesity

has anyone had these issues, any idea why or what the yawing is my concern ? Is this a side effect is it the lack of exercise the previous day - all input would be appreciated

thanks and keep working peoples
