The barriers - Cycling

All 3 of the events bring very different issues to how i train and how i compete in events so today i completed a 14 mile cycle and these are the issues i have to consider. Climate- it is raining at times with a cold wind so with thin blood by taking warfiran i feel tempertures of hot and cold in extremes so today concern is cold but if put on too many layers i find the sweat becomes cold & held in,making the cycle miserable.i have still to find a hot tempperature i cannot perform in. Start - no matter how fit i feel the 1st 10 minutes are always a struggle as device and therfore body find a consistent level, what i do find is because my heart rate will not go above 130 beats a minute i have no upper level despite feeling strong the effort just doesnt result in improved times. Distance- after cycling for 20 minutes i normally can tell if today is a good day or a write off, today felt disapointted due to time restraint only done 14miles. of all 3 discplines i find cycling the least effected by bad days. Today the cycle was good, i enjoy cycling on spin bike in gym but it just doesnt match a weekly long distance training ride so need to really review all of the above closely this winter if to achieve 26miles target as part of olympic distance
