''The irony is I won't be running at all this year due to an annoying groin injury, but I'll probably sneak in a couple of laps with the kids.''
Mr Davis is one of the founders of Highland Events, which runs several rogaine and endurance races, including the Northburn 100 later this month.
His team at the Relay for Life will be made up of family and friends, along with some competitors from events his business has organised. Some will run and some will walk laps of the course. He is a ''big fan'' of the 24-hour relay, which raises funds for the Cancer Society.
''I did the first one [in 2009] and really enjoyed it. There's a dedicated runners' lane this year so if you're going to go for a run this weekend anyway, you may as well come and do it with a supportive crowd in a `party' atmosphere.
''It's non-competitive, but there may be a wee leaderboard with who's done the most laps ... We'll see how it pans out on the day.''
Like the majority of people taking part in the event, Mr Davis has had people close to him die from cancer.
''What I like about the relay is that the money stays in Central Otago and actually goes to caring for those dealing with the disease.
''I'm happy to support this great cause and by doing so, encourage others to support it and its ideals - to remember those lost, celebrate their lives, and our own health, and fight back by taking proactive steps to choose a healthier lifestyle.''
He is keen to reiterate the benefits of a healthy and active lifestyle in general.
''Obviously, cancer can cut down anybody no matter what age or state of health they are. However, we can reduce our chances of many types of cancer by living healthy.
''Being active, in particular, has such great stress-relief properties and produces all sorts of natural therapeutic chemicals in your body.''
He ran 100km in the first Central Otago relay in 2009 over 24 hours with Greg Wilkinson, to ''test'' himself.
''... it was a real high point for me - for the last 10km I just cruised around at a nice comfortable pace and had random folks come up to me and run a few laps with me - it was my 'Forrest Gump' moment.''
More than 50 teams will take part in this year's event, which begins at noon on Saturday.
The teams are from all over Central Otago, Queenstown and the upper Clutha area. Some have 10 members, while others have up to 40. Everyone is welcome to take part in the event, whether they are in a team or not.
There will be music and entertainment throughout the 24 hours and nine school teams will compete in a ''top school'' series of events.
