Right you!
Here's my suggested training schedule, given you've managed what, 35 miles this week?. You need to make a bit of a jump and stop kiddin' around, or we'll be wanting our sponsor money back
week beginning:-
Next week - 3 rides, 45 miles
6 April Minimum 60 miles in 3 rides
13 April Minimum 65 in 3 rides
20 April Minimum 70 in 4 rides
27 April minimum 80 in 4 rides 2 back to back
4 May Minimum 90 in 3 rides - 2 back to back, 1 50 miler
11 May Minimum 90 miles in 4 rides 2 back to back (20 & 20, rest day, 2 back to back (15 & 35)
18 May 40 miles in 3 rides, a 20 and two easy tens back to back
You've got 210 miles to do in 3 days with a hangover on each one. So really you should also increase your units of alchohol each week too
