Thanks for Mr Tey for the photos.Will be trying hard to improve my timing for next, as this year i manage to lower my time nearly 20 minutes from last years time.

DEHYDRATED? NO SWEAT
A new study suggest that the fitter you are, the less hydration matters.
It is well known that dehydration detrimentally affects exercise performance and increases the thermoregulatory strain during exercise-at least in exercise science labaratory. But in the real world, athletes routinely experience moderate level of dehydration in training and c ompetition without any apparent loss of performance. Could it be dehydration affects exercise performance less in trained than in untrained individuals?
Researchers from the university of otago in New Zealand recently addressed this question in an intriguing study.
Six trained and untrained subjects each completed two exercises trials on separate occasions. In both trials they rode stationary bike for 40 min at 70% vo2 peak and then completed as much work as possible (i.e covered as much virtual distance as possible) in 40 min. But they performed one trial in a dehydrated state and the other in a fully hydrated state. Interestringly , heart rate was significantly higher and drifted upward more in untrained subjects during the first, moderate-intensity portion of the dehydrates
trial as compared to the hydrated trials, wheres there was no difference between this portion two trials in trained subjects. Performance in the maxsimum performance portion of the trials was negatively affected by dehydration for both groups, but the effects was twice as great for untrained subjects as for trained subjects.
Based on these results, the authors of this study, which was published Oct 6 edition of the British journal Acta Physiologica concluded, "Mild hypohydration exacerbated cardiovascular and thermoregulatory strain and tended to impair endurance performance, but aerobic fitness attenuated the physiological effects.''
