Given the magnitude of the event it seems appropriate to model the new course and discuss the weather forecast....

DAN EMPFIELDThu Jun 09 2022 David is the head of R&D at Profile Design and if you see something clever from this company there’s a very good chance it incubated in David’s brain. He’s one of the people in our industry whose judgment I trust at least as much as my own, and I know that when I ask him a question I’ll get a more fully fleshed answer than I could come up with on my own.David lives in New Zealand with his wife Nicky and their two daughters. He...

I've updated the IMNZ results files and generated a bunch of new comparisons for your edification. Or as a sleep aid - depends on how you feel about statistics. At the basic level of analysis, the average time this year was faster than the last few years:...

I suspect the limited daylight hours will cause more consternation than the environmental conditions....

Which is great news for bike fitters that care about doing a good job and consumers that wish to be more comfortable, particularly on their Tri/TT bikes....

Hayden is no stranger to spending days on end on a bike, having completed his first ultracycling event amidst the COVID ridden 2020 where he placed second overall. Badlands 2020, a 725km bikepacking off-road adventure, covering 15,000m of elevation and crossing the only official deserts in mainland Europe, was how Hayden got hooked on ultracycling.  Taking just over 52 hours to complete and not without a multitude of obstacles to tackle alo...

There were a number of factors at play, which I shall delve into (of course).Lets start by looking at the average splits over the years:...

There has been discussion of whether the new course will be faster or slower than the old. Unfortunately my analysis shows that theoretically it will only be faster if it is shorter or if the road surface is significantly better than I recall. There is a false flat (according to mapping software) on the way to the far turn that saps about 30s... Thu, 21 Jan 2021 16:05:38 +1300 http://www.speedtheory.co.nz/blog/#post61450
