Over 200 people will be getting on bicycles this weekend to raise money for a unique health service provided to homeless people in Dublin.

The cyclathon will take place on Dublin's South William Street and will see participants attempting to cycle 3,400km on 20 stationary bikes over a 12-hour period.

The aim is to raise funds for a replacement mobile health clinic for the Safetynet Ireland primary care service. This mobile clinic was founded in 2007 by Dublin GP, Dr Austin O'Carroll. It provides free GP care to homeless people and travels around 3,400km per year.

Last year, the clinic carried out almost 1,000 GP consultations.

One service user commented that homeless people would be ‘lost' without this service.

"My feet were quite bad from all the walking I did...It was someone who would listen and care. Your health and your wellbeing is everything, especially when you're dealing with homelessness. You couldn't get that service anywhere else," he said.

The event takes place on May 7. There will be music from some well-known bands and some well-known faces are expected to take part.

The organisers are looking for volunteers to cycle on the day. If you would like to get involved, email johnsansome@dubsimon.ie
