Hevizibivaly Duathlon, a first-time experience

Last weekend I participated in a Duathlon for the first time, and an interesting one at that: Instead of a cycling stage you’ve got rowing! Every year on 1 March they kick off the spring season in Hévíz by paddling about 10km along a brook starting from the thermal springs and then running back the same way.

Hévíz, or termálvíz literally means thermal water and it’s also the name of the town Hévíz where you can find the lake Hévíz. I was surprised to learn this is the biggest thermal lake in Europe and the second biggest in the world. The name of the race is a play on words in Hungarian because depending on where you break it up it’s either Hévízi bivaly (buffalo from Hévíz) or Hé vízibivaly (hey, water buffalo!), as if you were shouting. Apparently they used to drive water buffalo along the brook to clear out the water weeds.

It seemed like a fun idea to do the race on a tandem SUP. We have a second-hand one that we use with the kids on the Danube in Summer and the race rules don’t forbid two people on the same SUP, although I did get a call from the race organisers to double-check I hadn’t made a mistake filling out the form. All I needed was a teammate. I invited/challenged our local parish priest, Father Attila, to team up for the race; he’s really sporty and seemed like someone who’d be up for the challenge.

On the day I ended up going barefoot as the thermal water was pleasantly warm and by the end of the paddling stage we got the synchronised paddling down to a T. The water was really shallow, apparently much shallower than usual, and twice I got knocked down into a kneeling stance when the board’s fin got caught in some weeds. We were the only 2-person team to use a SUP, the rest were in kayaks or canoes, and we ended up being lumped together with the “touring vessels”.

The running stage was particularly tough for me. I’m not really a runner and although I’d run 10k before a few times I didn’t consider I’d start it off tired from holding my body steady on a paddleboard for 2 hours. No problem for Father Attila who didn’t even break a sweat. Okay, it was only 6°C at max, but he also goes for regular runs and is much fitter than me in this regard. Luckily the emphasis of the race is more on fun and several people were even strolling along instead of running, so we didn’t fare too badly despite me being completely out of breath by the end.

All in all it was a great event, pushing quite far out of my comfort zone but with a chilled and fun atmosphere, people cheering each other on during the race and so on. It’s definitely worth trying at least once, even if you’re not a hardcore runner or rower. I met some friends during the race who participate every year and it got me thinking, maybe I’ll sign up next year too… maybe with a bit more practice in advance though. 😉

FTR, these were the race stats I recorded to Strava/Garmin:
  

Sawing wood in the forest

This week we went wood chopping in the forest not far from the village. My family in-law use a boiler powered by a wood furnace to heat their house. That’s why it’s important to collect enough wood in advance, so that it can dry out enough to be used for firewood in years to come. They own part of some land covered in trees and with the foresters permission they collect some every year.

A small group of us drove out in the morning and cut down trees in teams of two: One person saws down the tree and Continue reading →

3D Printed Hungarian Cross

The Hungarian coat of arms features an iconic cross with two horizontal beams. In Hungarian it’s called “Kettős Kereszt” which translates to “Double Cross”, usually called the Patriarchal cross in English. This cross is present on other emblems around the area of Central and Eastern Europe too and has been featured on the Hungarian coat of arms at least since the reign of King Saint Stephen of Hungary.

Seeing as it’s a Hungarian national holiday today, in memory of the heroes and martyrs of the Hungarian revolution of 1956, everyone has their Hungarian flags out. I decided to do something Hungarian too, while trying out some tools for preparing models for 3D printing. So far I’ve been using Blender, because I have some experience with it, but it’s for creating 3D scenes and although you can use it to design 3D models for printing, it’s not CAD software. This time I tried Autodesk’s web-based program Tinkercad, which although lacking many of the features you’d get in a full-blown CAD program, is plenty enough for me to design simple things like this. Not being a mechanical engineer, I probably wouldn’t even know what features I’m missing!

The program is very intuitive to use. I put a few cubes on the workplane, stretched them out into intersecting rectangular boxes and exported an STL file for printing within minutes. You can see a screenshot of the result above. I also made a version with a hole cut out of the top so you could hang it on a key chain. That turned out to be as easy as putting a cylinder in one of the boxes, stretching it out of the top and bottom box faces and marking it as a “hole” in the model.

After scaling the model down to 30% so it fits on my print bed, the final print came out as shown in this photo. It took less than 10 minutes to print at 30% in-fill and seems pretty rigid. I’ve painted on the red, white and green of the Hungarian flag and will hang this up somewhere, who knows, maybe it’ll even be good for a Christmas decoration. If you’d like to print your own Hungarian cross you can download both of my STL files here:

In honour of the heroes! Tisztelet a hősöknek!
