Since another ride vanished from the calendar like a witness in a mob movie, I've been granted the rare 48-hour-rule exemption to lead this one solo. Yes----solo! Which means: 1.--No Rosemary-turns out she'd rather go to "fill in blank" than keep the senior brigade company.
2.-- No rescue squad-if you bonk, your only medical support is me yelling "hydrate!' from 40ft ahead. 3.--So no adult supervision-the club has essentially handed me the keys and said "try not to burn anything down". 4.-- No mechanical sympathy. If your derailleur explodes, I'll offer you emotional support and absolutely zero useful help. There will be one generous rest stop after Kilkare for free water refills! After that, we turn around and retrace our steps like a group of cyclists who forgot how loops work. Regroups at the top of the hills for the pace posted.
