Prague half-marathon

In 2024, Prague set a record for participants, with over 13,500 people at the finish. The previous editions had about 10,000 finishers, so there was a significant increase this year. More importantly, 57% of the participants were foreigners. The fact that the race is part of the SuperHalfs helps increase the number of participants.

On April 6th, the day of the race, it was hot in Prague. The temperatures reached 28 Celsius, and the sun was shining. These are not the best conditions for running a long distance.

The race route goes along the Vltava River and crosses five bridges between both sides of Prague. It continues in the old center through Venceslas Square and next to the famous astronomical clock. I am not a big fan of running on cobblestone. I prefer running on asphalt and visiting tourist attractions slowly and not during a run. The finish was in the same place as the start in Bubenské nábř. area.

During hot weather, it is essential to choose carefully how you dress

My race went okay in these circumstances, as I know how to run safely in hot weather. If you want to survive a race in hot weather, you need to do a few things: stop and drink water or isotonic at every hydration point, wear a cap, wear a tank top (not a T-shirt), keep the pace in the safe zone, have a couple of gels with you.

I finished at 2:14 without any incident. It was my third-worst time ever, but that did not matter as I checked my third super half race and did not focus on time.

I am very serious about the weather problem while running. In Prague, 102 people fell on the street during the race for different reasons. Of these runners, 36 went to hospital. The authorities declared a trauma plan (a local form of a disaster plan). There was a campaign hospital called Golem at the finish line in a huge tent with air conditioning and ambulances driving people there and into the hospital. I lost the count of fallen runners I saw during this race. It was much worse than in Lisbon. In fact, the sound I heard most during the race was the sound of ambulances. The medical help was very well organized. As a kid in the 80s, I remember watching a Czech serial called “Sanitka” ( The Ambulance) on TV. It was like seeing scenes from those series in Prague that Saturday.

There are many news articles about the problems at the Prague half-marathon, all in the Czech language. I found this post by a Cardiologist, Hanka Štefaničová, who, as a participant, described what happened during the race very well.

What I learned. At the end of the race, there was a problem. The runners who finished had to go on a tight corridor guardrail by fences for 200 meters to get the medals, and then they would get water, bananas, and other refreshments from the organizers. A few volunteers handled medals to racers at the end of these fences. But too many people finished simultaneously, and the queue of racers waiting because of this bottleneck was very long. Imagine the situation: you run under the sun for more than 2 hours, then you have to stop under the sun for 10 minutes or more to wait for the medal. If you get no water, you will collapse.

After getting the medals, some runners understood the gap, took water bottles, and gave them to the people in the queue. I drank 2 such bottles until I got the medal. That saved the other runners and me while waiting in the queue. I know those were ad-hoc volunteers because they all had finishers’ medals on their chests. They were not organizers. At the time, I took the medal and was happy to get the baggage and talk to Bogdan after the race. It didn’t cross my mind to stay and become one of the ad-hoc volunteers to give water to people waiting in the queue. In my mind, I was a participant who finished the race and not an organizer. Sometimes, you need to get out of your role, become human, and do what it takes to help others, even if no one has asked you or is not expecting you to do that.

With Bogdan, after the race. He had a good race in these circumstances, finishing in 1:50

Some statistics are relevant to what happened. For races with many runners, I look at the time of the runner who finished precisely in the middle of all the runners. If the race has 10k finishers, I look at the time of the runner who finished exactly at 5k at the finish. The table below clearly shows how external factors influence race results.

Lisbon18.03.2024132472:02:40
Prague06.04.2024135572:03:40
There are considerable differences in time when the weather is hot. The route in Warsaw is more difficult than the other 2. I can say that as I ran all 3 half-marathons (Warsaw in 2022).

I have some suggestions for the organizers. For example, they could give runners bottles of water instead of glasses. The volunteers were overwhelmed and did not have enough time to pour water into glasses to give to runners. At the finish, they could have more people to handle medals. Also, if possible, provide water to people once they finish and don’t let them wait under the sun. Set the check time posts in the farthest areas of the route, where people need to turn around. This is a simple mechanism to avoid cheating.

Despite the problems mentioned above, the organizers did a good job overall. A positive note for the area to leave and pick up baggage: it was the best organized I have ever witnessed. The rest of the nice things are expected for major half-marathons: SMS with your result, pictures after the race, refreshments during and after the race.

As for my plans, I traveled by plane four out of five consecutive weekends in March and April for events covered in this blog. It is time to rest and train before my next half-marathon in Helsinki in May.

Grenke chess tournament 2024

Five years ago, when I played in the Grenke chess tournament, I said to myself that if I had the chance, I would like to return to play this tournament in Karlsruhe. Years passed, and the Grenke Open was canceled until this year because of COVID-19 and some other reasons. This year, it was announced on short notice that the event would happen again. It is impressive what the organizers managed to do in less than two months!

The atmosphere of thousands of people playing chess simultaneously differentiates Grenke Chess Festival from other tournaments worldwide. These people range from the best players to absolute beginners, mainly from Germany and other countries.

At the start of the previous edition of the tournament, there were about 2000 players, but this year, after five years of pause, around 2600 players joined, making Grenke the biggest chess tournament in the world. This happened because the popularity of chess has been rising since the Queen Gambit series.

The festival consists of 4 different tournaments. The classic tournament had only 6 players, among the best in the world. The Open A tournament is open for players with an ELO rating above 2000. The B open is for players below 2000, and the C open is for beginners with less than 1600 ELO FIDE. All the open tournaments were 9 rounds played for 5 days: one round on Thursday, March 28th, and then 2 rounds daily for the next 4 days.

According to some statistics, were 935 players in the A-open, 1177 in the B-open, and 500 in the C-open. One interesting fact is that if the number of rounds is smaller than log2(n) -1, where n is the number of participants, you can end up with more than one player having a maximum number of points at the end of the tournament, which makes it hard to establish a winner. For example, in tournament B, log2 (1177) – 1 > 9 (number of rounds), but fortunately, there was just one winner with 8.5 out of 9.

The main playing hall

I played the B open with an ELO rating of 1857. I scored 5.5 out of 9 games: 5 wins, 1 draw, and 3 losses. Two of my losses were against players above 1900, including the last winner of the B tournament. The third lost game was against a lower-rated player in a completely won material and positional position. I guess I just relaxed too soon and blundered one piece and the game. I ended up at position 244 from 1177, which was better than my initial ranking of 303. As a result, I lost 3 ELO rating points. For comparison, 5 years ago, I was rated 1874 and made 6 points out of 9, losing 9 rating points and finishing 109 out of 797 players. The overall result was better last time, but the rating performance was better this time. This is possible when you play against people with higher ratings.

Overall, I am happy with my result because I don’t spend time preparing for chess.. Five years ago, I was more serious about training and playing than I am now. You can’t make progress in chess if you don’t work on it.

Part of the tournaments B and C area

Some sensation from the tournament was the draw obtained in round 2 by a junior Romanian FIDE master against the 9th player in the world, Arjun Erigaisi ( also the rating favorite of A-open). The winner of the classic chess tournament was Magnus Carlsen, the best player in the world. The winner of the A-open was Hans Moke Niemann, known in the chess world for the trial against Magnus Carlsen.

Some recommendations for people interested in participating in future editions. The playing venue is great, the space and the conditions are perfect. They have wooden boards and pieces for everyone ( they needed more than 1300 boards and pieces this time). The tables are big, the chairs are good, you have enough space during the game. The only downside is the noise. You can’t be silent in an ample open space with more than 1500 simultaneously. This was not a problem for me, but I saw some players wearing earplugs. This recommendation is good for people who can’t focus because of noise. Don’t come to Grenke if this is your first tournament. The reason is that 4 days with double rounds means intensively playing chess for 7-8 hours each day. It may be like running a marathon by an untrained person.

Excellent conditions to play chess in Karlsruhe

I also have some recommendations for the organizers: Send SMS/WhatsApp messages to players with the pairings for the next round. Make some announcements in English, not only in German.

The chess world has changed a lot in the last five years. Now, all the top tournaments have live coverage on YouTube, with Grandmasters covering the games. Recently, players of different strengths have come to play in tournaments with tools, stream their games online, and have someone else comment live on them. For me, this is useful as I can learn more from the games of a 2000 ELO-rated player (close to my level) than I can learn from 2700+ players.

I would happily return to this tournament because of the unique positive vibe and energy.

As in this article, I compared this edition with the one five years ago and chose to end with a song on this theme.
