Organisers are counting down to a spectacular Bogfest over August Bank Holiday weekend with events including the famous World Bog snorkelling Championships and a Bogathlon.

The team at Green Events are preparing to welcome thousands of visitors in the small Mid Wales town of Llanwrtyd Wells on August 29 and 30.

The town has developed an international reputation for organising unusual challenges in a series of both wacky and traditional events.

This year’s Bogfest will include live music across the weekend – starting on Saturday at 4pm and continuing on Sunday from around 10am until late.

The 'Chapel' Bogathlon on August 29 is a mini triathlon with a twist. The event comprises a 60-yard swim, two-mile cross country cycle and one mile run over testing, probably wet, terrain. Competitors must be over 14 years.

The 40th ‘Chapel’ World Bog Snorkelling Championships take place on August 30 - from 10am to around 3.30pm - and is expected to attract competitors from around the world, bidding to become the fastest bogsnorkeller over 120 yards.

The Summer Cider Cycle and MTB Chariot race takes place on August 15. The non-competitive cycle ride follows marked routes across the beautiful, local countryside and is suitable for riders of all standards, but there are special sections for the more experienced.

The MTB Chariot racing is for three person teams - one charioteer and two on mountain bikes replacing the horses. Special chariots, built using traditional, ancient Roman mild steel, vulcanised rubber and welding techniques, have been commissioned for the event and will race against each other and the clock to determine this year's world champions.

This race is expected to attract around 10 teams and bikes are provided free of charge for this event. Entries for the MTB Chariot Race and Summer Cider Cycle will be accepted on the day or can be registered at www.green-events.co.uk
