80k you must be taking it serious
I do it for leisure john, im not one of these cycling nazis that fly along in top gear trying to beat the clock, i couldn’t give a fuck if a four hour cycle took me eight hours to do, i enjoy it and youd be amazed of the things and beauty youd see that you never knew existed.
If i was you id go onto one of them cycling tracks at the canal and practise if you dont like the roads.
The greenaways are great, i was hoping to do the Waterford one this year but the pox has put it on hold
