We are delighted that Island Ferries have agreed to give all our Cleasathon 2014 participants a rate of €16 for a return ticket when travelling with them from Ros an Mhíl to Inis Oírr for the event. Please note however that you have to pre-book by 3.00pm on Thursday 10 April to avail of this rate. Full rate applies after that time and date.


We regret that this year's Advenure Run is now being cancelled for safety reasons due to continuing swells and high tides.   However the 10K road race is going ahead  and is much tougher as it has a new steep climb. The  5K road race is also going ahead. We apologise to all for this. 

2014 Cleasathon on Easter Saturday 19th April.      

The three options for Cleasathon 2014 are:                                                                                                Adventure Run - Starting Time: 1.30pm.   This 10k circuit of Inis Oírr Island is mainly off road on an often rough stony track taking in iconic sights such as Inis Oírr lighthouse and infamous "Craggy Island" shipwreck. Even tougher this year as recent swells and storms have created new obstacles and some sections follow a different route.                        

10k Road Run - Starting Time: 1.30pm. This is an undulating road run over the peaceful scenic island of Inis Oírr with spectacular views of Loch Mór and the Cliffs of Moher. This year a new uphill section in this 10k guarantees that it is definately no walk in the park!                                         

Twisted 5K Road Run - Starting Time: 1.30pm. This takes in some of the beautiful hilly routes of Inis Oírr.

Our aim at Cleas Teo. is to enhance life on our island of Inis Oírr.

To this end we provide a public transport service with our bus Síob an Phobail, a year-round daily service.

We support the promotion of the Irish language through our Translation Service Business to clients and the general public.

We sell hand harvested island seaweed products Fiúntas Feamainne including carrageen, dulse and bathing seaweeds. 

We repair the Island's Seashore Walkways and ensure they remain open throughout the year.        

We organise the annual Easter Cleasathon-Inis Oírr running events.

We grow willow and produce traditional and modern Items of Basketry

The world famous model Aran Currachs in various sizes are hand crafted by our team and sold here.  

The multi-coloured traditional belt the Crios is also produced by us.

Our Cleas Crafts outlet, situated upstairs in our Áras Éanna premises, stocks crafts produced by local island craftspeople and remains open throughout the year.                                       

Through our Taste of the Gaeltacht we cater for groups keen to sample our island's heritage.

We also provide Guided Walking Tours, available all year around.

Through our Environmental Projects we endeavour to keep the many walking routes, sideroads and wells on our island  accessible and litter free.                                                                                                

More information on all of these on 'Island General Info' page.                                              


Why Cleasathon?

Through Cleasathon we want to reveal the magnificence of Inis Oírr's frontier landscape. For this reason we continue year in year out to remove the unwanted flotsam tarnishing the beauty of our island's natural environment. To increase accessibility to the back of the island for islanders, visitors and future adventurers we also cleared a walking trail. Our powerful neighbour the Atlantic Ocean ensures our continuing efforts as mighty winter swells lash the coastline disturbing trails and depositing rejected rubbish onto the island's stormbeaches.  

Cleasathon is a Cleas Teo. project. Money raised through this event will be used to continue the above work and a percentage will be donated to a national charity.

In 2012 & 2013 the Aran Islands RNLI were the recipients of this donation.
