This tradition was established in the Czech Republic by the Czech AIDS Help Society (CSAP) and the online dating sites iBoys.cz, iGirls.cz. The Prague Pride organization joined the organizing team in 2017 – the event was renamed then Fun&Run and was moved to the Stromovka park in Prague. The participation has been increasing ever since. 304 runners joined the 7^th edition, and 514 announced their participation for the 8^th edition, 533 registered for the 9^th. In 2019, the run moved to Letna public park and iBoys and iGirls stepped down from organizing team and became media partners. In 2020, we will run in Žluté lázně (Yellow Spa) sports grounds located by Vltava river.

The proceeds from the starting fee are used to support the online counselling service Sbarvouven.cz and Dům světla (House of Light), a service for HIV-positive people. Alongside with the main run there’s also a children’s race, which is admission-free.

Fun&Run is presented as a race against homophobia and the stigmatization of HIV-positive people. At the site there are mobile labs where the Czech AIDS Help Society (CSAP) offers free HIV and syphilis tests. In 2018 we had 79 people tested, in 2019 the number increased to 141.

In 2017 and 2018 Fun&Run was held under the auspices of the Mayor of Prague, Adriana Krnáčová. Fun&Run 2019 got the auspices of the Minister of Health Adam Vojtěch and the Mayor of Prague Zdeněk Hřib.
