In a grim start to 2015, this January has seen more cyclist fatalities on Britain's roads than in any year since 2008.
Thirteen riders have died so far this year, the most since 2008, when the whole of January saw 14 cyclist fatalities.
Since 2003 the Department for Transport's annual report on road casualties has included a breakdown of casualties by month and road user type.
Those figures reveal that the average number of cyclist fatalities in the first month of the year is 9.8, so by the middle of the month you'd expect five or so deaths.
It's worth bearing in mind that the average masks a large variation, from 16 in 2006 down to just 3 in 2010.
Nevertheless, it's hard to avoid the feeling that there's been something unusual about the first two weeks of 2015. Only an expert statistical analysis would reveal if that's the case though, as happened when six riders lost their lives in two weeks in London in 'Black November' 2013.
In a paper for the Royal Statistical Society journal Significance, Jody Aberdein and David Spiegelhalter concluded that in an eight year period there was only a 1 in 40 chance that 6 riders would die in a fortnight in London. There really was something unusual about that spate of deaths.
The relatively mild start to the year may be a factor, with the general lack of snow and ice perhaps enticing more riders out to risk the short days and long mornings and evenings.
Prof Spiegelhalter made the mathematical tools he and Dr Aberdein used to analyse the London spate of deaths available on his blog. If anyone who's a lot better at maths than us would like to apply them to this latest series of fatalities, please let us know.

We are aware that some readers find reports of death and serious injuries to cyclists distressing. We will continue to report them from police reports, but unless there is something unusual about the particular incident, we won't promote them through social media.
We believe every cycling death is one too many. The number of deaths and serious injuries has declined in recent years, but the Dutch experience shows that the rate could be much lower. We encourage readers to join organisations such as the CTC, LCC or your local cycling campaign group to fight for a safer environment for cycling.
Our official grumpy Northerner, John has been riding bikes for over 30 years since discovering as an uncoordinated teen that a sport could be fun if it didn't require you to catch a ball or get in the way of a hulking prop forward.
Road touring was followed by mountain biking and a career racing in the mud that was as brief as it was unsuccessful.
Somewhere along the line came the discovery that he could string a few words together, followed by the even more remarkable discovery that people were mug enough to pay for this rather than expecting him to do an honest day's work. He's pretty certain he's worked for even more bike publications than Mat Brett.
The inevitable 30-something MAMIL transition saw him shift to skinny tyres and these days he lives in Cambridge where the lack of hills is more than made up for by the headwinds.
