I added miles in 20-25 increments. My thought process was (in your case) I did 27 km so I KNOW I can do that....so I'll just add another 27 kms. If that works for you, you would be doing a metric century in 4 wks give or take.

and I gotta ask coz darn it Audio - now you've got me thinking: how far is an imperial century?


does anyone know of any Long Distance Riders Anonymous meetings in my area?
