What an analysis of millions of marathon race records reveals about marathon pacing based on sex, age and ability.

Hitting the wall is the great leveller in the marathon. …


An exit-analysis as restrictions are lifted during Ireland’s second COVID-19 wave, and what this means for Christmas and beyond.

Now that we know how restrictions will be lifted in Ireland over the coming weeks, and with a special COVID edition of the Late Late Toy Show behind us — truly a Toy Show for the ages — it’s beginning to feel a lot like Christmas. That’s great. Just what…


Why we need help to overcome our congitive biases if we are to live safely with the coronavirus.

Over the weekend I have been thinking a lot about what happens next, as we come out of Level 5, and whether we might be able to live safely with the virus, rather than bounce in and out of further lockdowns. Let’s face it, we have not been doing so…


A analysis of the taper patterns of recreational marathon runners and their implications for race-day performance.

The taper is an important part of marathon training. It refers to a period of lighter training in the 2–4 weeks before race-day. The basic idea is for the runner to reduce their training load in a controlled manner so that their body can better recover from, and adapt to…


An Analysis of 7-Day Cases by Age Group during Christmas Week

COVID concern is justifiably high at the moment here in Ireland, what with all of the indicators moving in the wrong direction, and our UK neighbours struggling with a new and more contagious strain of the virus, leading to travel bans and the sudden re-imposition of more strict lockdown conditions…

In Ireland, we are well into the second coronavirus wave, along with the rest of Europe, but it is surprising to see just how different this wave appears to be, when compared with the first wave. …


The road to Level 3 for Dublin and where it may lead.

If we are not all in this together, then we are not in it at all.

By way of a follow-up to Friday’s post, which discussed some of the early signs that Level 3 lockdowns are working in Dublin and Donegal, this post takes a closer look at Dublin’s recent…


A look at what we have learned from recent restrictions and their ability to change the course of the virus.

Will our current Level 3 restrictions allow us to regain some control over this virus? Or will they only serve to delay a move to Level 5? This is a question that has dominated the past few days.

Obviously we don’t know what the future will hold, and it can…

Updated: 7/10/2020 to adjust the time for confirmed cases to be hospitalised from 7 days to 14 days and from confirmed cases to fatalities from 14 days to 28 days.
