Mourne Seven Sevens

We are going to give the Mourne Seven Sevens a shot again this year. For those not familiar, this route covers the seven peaks >700m in height in the Mourne mountains. It's approx. 28km and 2,130m ascent. Yes, you read the correctly, 2,130m. Please only sign up if you are capable of a hike of this level at a good pace. This is not for the faint hearted. On a good day it's one of the finest hikes in the country. I hope to do a couple of big hikes leading up to this for a bit of training.
If anyone is a self navigator and wants to do it at their own pace, that is fine. Or if anyone wants to do a shorter version, that also fine.
