I have added a new feature to JSEM TU!: the option to put a logo on your profile picture. And that got me thinking — why not put it on the website as well, for people who do not have the app? So here it is: FB profile picture.
JSEM TU!, the app for cold-water swimmers, has been available to download from Google Play since 4 September 2026. We updated this article on 12 September to reflect the current version. It is in public open testing in Czechia and Slovakia. Accounts can now be created from age 9; anyone under 16 needs a parent or legal guardian's approval before using the app.
The severe floods in mid-September caused widespread damage. Unfortunately, U Žida weir, where we meet for winter swimming, was not spared. Thankfully, repair work is already under way as I write this on 29 September. It mainly involves dredging and removing stones that have completely filled parts of the river channel. There is a good chance the site will be ready for the start of the new season, allowing us to swim safely at “our” weir throughout the winter.
We also have a Facebook group. Think of it as the clubhouse we do not have in real life. It is just for those of us who actually come to the river and know one another.
Because of new COVID-related restrictions, our group winter swims at U Žida are temporarily suspended from 1 March 2021. Thank you for a wonderful season so far. Please respect the restrictions; I look forward to meeting again when circumstances allow. Ota
Covid measures limit outdoor sport to six people in one place at one time from Saturday 19 December 2020. Our regular swims will continue, provided we respect this rule.
Eased Covid restrictions now allow sport in groups of six, and we made full use of that on Monday. We are keeping our distance on the bank and in the water, but above all we are enjoying ourselves again :-)
Level 4 of the PES alert system allows outdoor sport in groups of up to six. We are pleased that Covid restrictions are gradually easing and we can swim together in small groups again.
Until restrictions ease, I am offering swims at our usual times for beginners who enjoy it but are not yet ready to manage on their own. Maximum six people.
Ladies ❤️ and gentlemen 👍, Saturday’s swim will still take place as competition training, with up to 130 people. From Monday, there will be two consecutive sessions of no more than twenty people each, as in spring. It is straightforward: beginners and anyone in a hurry go first; experienced swimmers and runners follow once the first group is out. The upper railing will separate the groups, with a great view for photos and encouragement. I will explain everything there tomorrow. See you by the water ❤️👍
