i started 'my' half iron program three weeks ago. it is tough to start the week of christmas and i missed one session of each discipline. the next week i was spreading all that mulch and in hot weather and missed one bike and a run. then last week i started a new job and my ear was still playing up so i missed two swims. it feels like forever since i swam in a pool but it has only been 13 days. i think that is the longest break from the pool in three years. one problem i have solved is being bitten by the cramp shark. i was at a point where it was cutting my swims short and leaving a dull ache in whatever muscle it bit. then i took magnesium and not one attack since. magnesium works in conjunction with calcium so i have started taking that as well. i thought i had a pretty good diet. and this was almost instantaneous. i changed nothing else and the cramp shark is gone. i am still having trouble with my bike fit and i am starting to regret changing anything. i can put up with quite a bit and i am willing to persevere but at times i just want to either throw my bike in the bushes or sit and cry. my shoulders kill me and now the sides of both knees are just painful. i am going to the physio to get it checked out and get a second opinion. i was riding 90k okay and now struggle to get to 75k. boo hoo.
