It would be fair to say, that there are a few of us in the geocaching community that have a competitive streak in us. But the beauty of geocaching is that often – the competition is with ourselves!

I never forget when I first discovered what a challenge cache was – it was like a whole new world of geocaching opened up to me and I was in awe of how rich, yet diverse the game really was. I had many late nights after that moment, delving into the possibilities, the statistics, the challenges and tried to see if in my newbie status of geocaching, I actually qualified for any…. sadly I didn’t – BUT I had a whole new appreciation for what I COULD achieve.

With the Whittlesea Mega only a few weeks away and with the recent publication of a new challenge series (Whittlesea Challenge Wander Series) available, I thought it was an opportune time to connect with one of our challenge greats – Adriaan Homburg aka ahomburg on his experience on what makes challenges so exciting.

Thanks for chatting with me ahomburg, firstly can you share with us when you started Geocaching?
I registered in 2006 but never tried to find a cache until 2010 when I was heading out for a BBQ with my family on Australia day. There was a Muzza cache called Dandenong Ranges Track #3 (GCC4F2) which was close by. The rest is history!

You have a great reputation for creating and achieving lots of different types of challenge caches – for those that are new to the game, can you explain what is a challenge cache?
A challenge cache uses the same icon as a geocaching puzzle or mystery cache and it is usually at the listed coordinates and will have the word “challenge” in its title. But there is no puzzle to solve – rather it has a challenge for you to meet!

So finding the container is not enough to claim a smiley. Within the description of the cache, it will outline what you have to achieve or what criteria you have to meet in order to qualify and complete the challenge.

This could be as simple as finding a total of 50 caches, or it could be that you have to find 5 large caches, or attend ten events. There are a wide range of challenges available some suitable for beginners, where as others may be for more seasoned cachers and could take years to achieve.

How do you find challenge caches? Is there a list?
There are a few ways to locate challenge caches. The easiest way is to go to project-gc.com where you can bring up a map or view a list of nearby challenges.

You can sign a challenge cache log book at any time. It is important to note that if you find the actual cache before you qualify, you can add a ‘write note’ to the cache confirming that you have signed the physical log and that you intend to work towards the challenge. Once you meet the requirements of the cache, you can then follow up with a ‘found it’ log and claim the smiley.

Sometimes you qualify for a challenge cache before you find the actual cache. If this is the case you can add a write note with your evidence (from project gc checker as an example) of how you meet the criteria and show your intention to sign the log at a future date. This can then be followed up with a ‘found it’ log when you sign the actual log.

You mentioned project GC checkers to see if you have qualified, what is a checker and how do I use it?
All challenges since 2016 must include a project-gc.com challenge checker. Challenge checkers are used to see if a you qualify for a challenge and an easy way for the cache owner to know if you have filled the challenge criteria. These are all on project-gc.com, there is usually a link on the challenge cache page to see if you have qualified. It’s just a matter of opening the link and clicking on “Run Checker” and crossing your fingers. 🤣

What are some great challenges that beginners should start on?
The best type for beginners is to find a certain number of caches, these are great as you don’t have to think too much about it. You can then move to the more complex ones like finding a certain number in a particular month.

BettyBoo3747 has some great challenge caches around the Beechworth Area like ‘Who Hid That There’ (GC4GZXH) where you have to collect 26 caches alphabetically from A-Z by Hider name. Perhaps even some of Sharkiefan’s challenge caches like (GC5AKTV) The 50 Souvenir Challenge Cache.

Geocaching Victoria also has quite a few listed on their website to help get you going. So be sure to check out that challenge web page.

What have been some of the favourite challenge caches that you have completed?
Most challenges are fun. My absolute favourite are ones I don’t qualify for and have to work towards.

The original Unloved challenge, (GC3KWWQ) Spread the Love Challenge – where you had to find caches that had not been found in at least 183 days (6 months) it was great fun and always great to find these with a focus on caches that had not been found in the longest amount of time.

The other one I really like is the map based ones like (GCY98X) Victoria Country Road Atlas Challenge, where you have to find one cache on every page of the Victorian Country road map book and of course the (GC5DFFR) Victorian LGA Polygon Challenge where you need a cache in all the local government areas in Victoria.

You have such a high number of finds, and an experienced cacher, is there still challenges you are working towards that have not yet qualified for?
Sadly in recent years the guidelines around publishing challenge caches have changed whereby all challenges need 10 local qualifiers to be published. Often I find that I already qualify for new challenges, but there has been a few recently like the 12 in every Victorian LGA and the 20 in 80 LGAs which have given me something to work on.

But in recent months I have enjoyed creating new challenge caches for others, like the recently published Whittlesea Challenge Wander Series.

Thanks so much ahomburg – I certainly look forward to working towards your more recent challenges, but to be honest I have many of your older ones still on the go too!

I must say I am a fan of the project GC challenge tools, because once you have added a write note to a challenge cache and run the checker, it tracks what challenges you are working on via the profile statistics… and lets just say my list is long!
