Forget you 100m sprint or and your bike races - when it comes to competitions, it seems wacky is the way to go.

With Shelley and Shepley hosting their first ever community trolley dash , we thought we'd take a look to see what other unusual events get competitive juices flowing.

Trolley dash not tickling you fancy? How about sailing a Yorkshire Pudding boat? Or lobbing a bit of black pudding as far as you can?

Here's some of the weird and wonderful competitions you can try:

The Yorkshire Pudding Boat Race

The much-loved Yorkshire Pudding is not just the cornerstone of a good Sunday roast, it's also a boat, if you make on big enough. Apparently. The Yorkshire Pudding Boat Race, organised by arts venue The Shed in Rydale, North Yorkshire, sees youngsters paddle along in boats made out of Yorkshire pudding (and some wire mesh, for stability). Creator Simon Thackwray said he was sat in the pub one Sunday afternoon, watching plates of Yorkshire puddings and roast beef go past, when he wondered about floating down the river in one. Sadly, a race wasn't held in 2014, but hopefully it will return next year.

Ramsbottom World Black Pudding Throwing Championships

Yorkshire and Lancashire thrash out their ancient rivalry by seeing who can chuck black puddings 20 foot in the air. And that's not all - they lob the black pudding in an attempt to knock off the pile of Yorkshire puddings off a specially-built plinth. The bizarre competition has been going on since the 1980s, and takes place on the second Sunday in September.

The Great Knaresborough Bed Race

This race, held every June in the quaint North Yorkshire town of Knaresborough, is a road race where teams speed through the narrow streets - and through the River Nidd, at one point - pushing along a bed frame. The niche event is preceded by a themed parade, where competitors dress their beds accordingly and walk alongside them. The annual race attracts thousands of spectators, and raises

The World's Biggest Liar Competition

Held at The Bridge Inn in Santon Bridge, Cumbria, the World's Biggest Liar Competition is held in Novemer, inspired by 19th century publican Will Ritson, who used to tell some right whoppers to the regulars. He once claimed that the turnips in Wasdale were so big that after the dalesfolk had "quarried" into them for their Sunday lunch and that they could be used as sheds for the Herdwick Sheep from the fells. The competition seeks to find someone whose stories match Auld Will's.

The World Coal Carrying Championships

What could be more northern than lugging sacks of coal about to win a prize? On Easter Monday each year, men and women do just that, racing with their coal from the Royal Oak pub in Ossett to the Maypole Green in Gawthorpe Village, a distance of 1012 metres. Men carry 50kg of coal, while the women carry 20kg. The race was formed by an argument in the pub in 1963 between two men about what was fittest - which was then decided by the first ever coal carrying race.

The Meltham Murder Maniac Road Race

This punishing race returned in May this year after a 17 year hiatus. While the race is only two miles long – the ‘Murder Mile’ uphill and the ‘Maniac Mile’ downhill – the road’s gradient and unforgiving tarmac makes it a hair-raising and knee-grazing challenge. The race was invented by former athlete and coal carrying champion Terry Lyons who has lived on Wessenden Head Road for 40 years - and featured on BBC Record Breakers in the 1990s with triple Olympic medallist Kriss Akabusi.

Cheese-Rolling at Cooper's Hill in Gloucestershire

And of course no wacky races round-up would be complete without the infamous Gloucestershire cheese-rolling event, where competitors throw themselves down Cooper's Hill after a rapidly accelerating wheel of the county's finest double Gloucester in the hope they can catch it and eat cheese on toast for the rest of the month. The event always sees a few unlucky competitors pick up an injury or two - the highest count was in 1997, when 33 cheese chasers came a cropper. Ouch.

Holmfirth Duck Race

The Tour de France whizzed through Holmfirth this year - and spectators also got to see more unusual race take place - the annual Holmfirth Duck Race! The wacky event - which embraced the Tour de France theme - saw 10,000 yellow plastic ducks tipped into the river for a race down to the Sands, Holmfirth.  Organised by the Huddersfield Pendragon Roundtable, the event has attracted a cult following over the years.
