Returning for it's 7th year this year is the Great Island Run, 10 mile race in Cobh, Co. Cork. (also including a 4 mile race). Expect around 600 runners for the 10 mile, and 250 for the 4 mile.
All the money raised from this race is donated to the Irish Cancer Society.
This is a tough enough route, not the worst, and certainly good training. The first 2 miles are fast and downhill, the next 4 miles are pretty challenging. From mile 6 to the finish it's pretty flat, except for a slight incline around 8.5 miles. Also a nice downhill finish with views of cork harbour.
The 4 mile starts downhill and follows the last 3 miles of the 10 mile route.
Entry for the 10 Mile is €20 online or €25 on the day. Entry for the 4 Mile is €10 online or €15 on the day.
Just to reiterate, this race is run for the Irish Cancer Society, no profits are taken by organisers.
