The game curling involves players sliding heavy granite stones across an ice rink, aiming for a target of four concentric circles; teams of four take turns to deliver their stones, with 'sweepers' brushing the ice to create a layer of moisture under the stone in order to affect its speed and direction of travel.
Curling is a very tactical game, often called Chess on Ice.
In 2013, the event saw 76 teams compete on 19 different open-air rinks over 4 days. After 5 rounds of throwing stones, frantic brushing and the urgent shouting of instructions, the trophy was won by Select Crystal Zurich.
In 2014, the trophy was lifted by Team Adrian Rieder, in 2015 Glarus Open Air lifted the cup, and the 2016 tournament was won by Visp Leiggener
The 25th Horu Trophy, organised by Curling Club Zermatt, was held in January 2017. Dates for 2018 are yet to be confirmed.

Held in Zermatt and Valle Nevado, Chile, the teams battle it out for a silver metal ski boot trophy and considerable bragging rights. There are two aspects to the competition: big mountain skiing and backcountry slopestyle.
Big mountain skiing involves a one-time shot for each rider at a steep off-piste mountain run which includes a number of cliff jumps.
Backcountry slopestyle involves the riders taking on a series of sculpted jumps and spinning, somersaulting and twisting in the air.
The 2013 competition was won by the European team, led by captain Kaj Zackrisson. The US skipper, Cody Townsend, got his revenge in 2014, when the Americas won 9-7.
In 2016, the event took a break from Zermatt. It was held in Grandvalira, Andorra between 30 January and 4 February 2016, and organisers have just confirmed that it won't be held at all in 2017. Let's hope it returns in 2018.
The Festival features over 30 artists on five stages. The Marquee Stage (aka Main Stage) sees the headline acts. Built on the tennis courts in central Zermatt, it has a diameter of 48 metres and a crowd capacity of 2000.

Developed by Simon Biner and Harry Lauber, and now entering its 24th year, the Matterhorn Eagle Cup attracts around 150 golfers.
The usual rules of golf have been modified somewhat: the hole has a diameter of 75 centimetres; there is no ‘out of bounds’; the ball can be placed after every shot (but no closer to the hole); and players are only allowed to use three clubs (a 3 wood, 7 iron and pitching wedge are recommended).
The day after the tournament sees another event, Pimp up your score, held at the Matterhorn Golf Club in Randa; this is a double fourball best ball competition, with a double shotgun start (morning and afternoon).
The last Eagle Cup was held on 30 July 2016. The date for 2017 is not yet announced.
