But I was still surprised to read someone suggesting they go faster in the winter. The only time this happens to me is when I’m out during a windy winter day and catch a nice tailwind.
But I thought I’d check the Strava data from my site. Which months have the most KOMs? Checking that removes at least one variable, different roads. First I had to update my site to store the KOM date for each segment then I had to grab some data. I chose segments in the UK, removing those that were less than 0.5km (too easily messed up with dubious GPS data) and removing segments with less than 100 riders (not competitive enough) and this is what I got.
This is a fairly small sample but it certainly suggests the summer months are the best time to grab a KOM, which also suggests the summer is the fastest time of the year for cycling. But then a thought crossed my mind, people tend to cycle more during the summer months, so perhaps it’s unsurprising that most KOMs are achieved then. So my conclusion is that I still have no idea and more research is required. And there are too many variables…
For my own recollection, this is the SQL I used to grab the data
SELECT MONTH(KOMDate), COUNT(*) FROM segments
WHERE Country='United Kingdom' AND
KOMDate IS NOT NULL
GROUP BY MONTH(KOMDate)
ORDER BY MONTH(KOMDate)
