Race is going to start in an hour and a half. The temp is a cool 4 deg outside and the sun might even come out from behind those clouds!!! I am wearing a long sleeve polypropylene shirt and a pair of short pants. That should keep me warm and dry. I forgot to replenish my supply of energy gel since the Army Race half-marathon in September. Hopefully, the three remaining packs plus the Gatorade/water from stations along the way will prevent me from "hitting the wall".

貼堂佳作【哈利哥跑馬拉松】
(哈哈! 多謝Space兄送來的打油丶加油詩!!)
哈利哥跑馬拉松
開步之時人頭擁
有老有少齊跑步
上高落低無亂籠
哈利哥跑馬拉松
沿途秋葉輕風送
訓練有素腳頭勁
不徐不疾好輕鬆
哈利哥跑馬拉松
良朋知己喜相逢
祇重參與唔包尾
談笑用兵不論功
哈利哥跑馬拉松
嗜悲賦詩來歌頌
左度右度好過癮
夠鐘寫完又開工

p.s. Happy Thanksgiving
Xiao Zhu: 謝謝!! 加多了油,跑也跑得起勁點!!
Best Actor: It was only minus 2 deg C at the start and there was a blistering wind thru out. But I had fun and finished the half-marathon in good time, within my expectatoin.
Thanks!!
:)
Space: Hahahahaha !!! Thanks a lot :)
借問聲哈利哥：“But I had fun and finished the half-marathon in good time, within my expectatoin.”
半馬拉松是 21Km Good Time 即是幾多呢？
香港渣打馬拉松2010228 舉行，full marathon 全馬賽事將設立新路段，加入由青衣至長沙灣的一段8號幹線新大橋，Stone Cutters Bridge (昂船洲大橋) 。截止報名日期為12月31日。

Space呢首打油詩寫得好呀！
Space:
Thank you for the info abt joining the marathon race in HK. One of these days, one of these days ...
As to the question re completing a half-marathon in "good" time:
Obviously, "good" is all relative. This year, the time varies from 1 h 18 min for the number one guy to 4 h 05 min for the last person !!!
Also, age is a factor. For example: I would say 4 h 05 min will be considered "very good" for someone 75+ years old !!!
xiao zhu:
Yes, I agree. He was good !!!
Oh！ “For example: I would say 4 h 05 min will be considered "very good" for someone 75+ years old !!!”
I wished to take the lazy way so I employed the mathematical method of "proportion" "prorate" or "pro rata". But I didnt know the age of the champion. So it was not working.
Space:
I think the age-time relation is non-linear. So, even if you know the first and last data pair (A1,T1) and (An,Tn), you still will not be able to prorate time Ti at age Ai.
Perhaps if you collect enough data at a large race event, such as those held in Europe where the number of participants is > 30 000, you may be able to draw a graph and predict the average time of a particular cluster (age group). But even then, there are guys like Lance Armstrong who has aged, but at 38, still has the performance of someone 15-20 years younger.
Ref: Wikipedia
Lance Armstrong / Physical attributes:
Armstrong has recorded an aerobic capacity of 83.8 mL/kg/min (VO2 Max), higher than the average person (40-50), but lower than other Tour De France winners, Miguel Indurain (88.0, although reports exist that Indurain tested at 92-94) and Greg LeMond (92.5). He has a resting heart rate of 32-34 beats per minute (bpm) with a maximum heart rate of 201 bpm.
Oh I have already thought about that thoroughly Hari big brother.
The X-axis be the age and the Y-axis be the time. The curve should somewhat resemble a V or a U，the very bottom point should be the age and his/her recoreded time of the champion. By the sum of least squares I believe a curve can be plotted with good approximation.
What you said above proved to be consistent with my assumption and theory. ^_*

We are consistently being highly technical and analytical while other readers are consistently scratching their heads !!
So what's your question again?
