我喺六月二十一日參加咗喺加拿大文尼吐巴省其中城市温尼泊舉行嘅半馬，賽事舉行前的一個禮拜都重係十幾度，但喺比賽嗰日氣温竟然錄得破紀錄嘅最高三十度，加上九成賽道完全暴露喺陽光之下，跑到我攤攤腰，幾次想放棄，成績亦係最差嘅一次．據報導，嗰次賽事破咗不適入院人數紀錄。而根據當地醫學權威表示，當日溫度升至30度，加上濕度為歷屆最高，不適合舉行長跑。結果大會在十一時開始將賽道封閉。以下為其中的一份報章嘅賽後報導。
Sunday's sweltering heat was a challenge for many Manitobans more used to the cold up until last week. Running mates Gail Brigham, 53 and Jill Naird, 50, train together for the half-marathon every year. During their last major training run in Gimli two weeks ago, they were bundled up in tuques and mittens. "Two weeks later and we're like 'oh my goodness,'"said Brigham."It was really hard for the Winnipeg runners, we didn't have much time to acclimatize." Officially, it was "white" hot before noon in Winnipeg, and marathon organizers started winding down the event. By 11 a.m., the temperature hit 30 C but felt even hotter with the humidex, said marathon executive director shirley Lumb. when the conditions reach the "white" level, organizers start closing the course, she said.
More runners ended up in the medical tent this year than in years past, said marathon medical director Dr. Edward Pilat. "We kind of expected that because of the weather and the inability to acclimatize," Pilat said.
跑步會唔會跑死人呢？加拿大某大學就呢個問題做咗一項研究，將完成賽事嘅長跑選手嘅《心酵素》作分析。而《心酵素》同心臟病息息相關，《心酵素》愈高表示心臟病病發嘅機會愈大。最後發現，完成賽事嘅長跑選手嘅《心酵素》讀數等同一個患嚴重心臟病嘅病人。換句話講，跑步真係要量力而為，千祈唔好死頂，亦要順應個人體質，研究適合自己跑嘅路程距離。
