Does an equivalent to "the swedish classic circuit" exist in other countries?

I know this isn’t just about running but I hope the mods accept it anyway.

The swedish classic is a combination of 4 different long distance event held during a year. Every year thousands of swedes compete in the four races to be a worthy finisher of the Swedish classic. It races included are.

Vasaloppet 90Km Cross-country Skiing Held on the first sunday of march. The race starts in Sälen and ends in Mora. The race was inspired by a journey which Kin g Gustav Vasa made in 1520 when he fleed the danish soldiers.

Vätternrundan 300Km bicycling Held in June every year. The race start and ends in Motala and circles around Vättern, the second largest lake in Sweden. Around 23000 people compete every year.

Vansbrosimmningen 3Km Open Water Swimming Held in Vansbro during June every year. According to me and lot of others the easiest part in the classic.

Lidingöloppet 30Km Cross Country Running Held on the island Lidingö outiside Stockholm during the last weekend of September every year. Due to its hilly profile it is considered almost as tough as a marathon. The most feared part of the race is Abborbacken after 25km which features approximately 10% elevation during 550m.

Half and thirds of also exist of every race and or included in the half classic and womens classic. It would be interesting to know it any similar things exist in other countries.
