I am doing the Pan Mass in 3 weeks - 111 hilly miles. I have been riding seriously since March, withoiut being super fit before hand.

Did my first century in May. I have been following a cycling book by DeDe Barry and just finished the hill climbing interval program. I went to the Berkshires to practice on hills this weekend and was frankly disappointed in my performance. Still a slow 4 MPH on hills, although I now do 18 MPH on rolling hills. Spiked 174 on my HRM on the first hill

I have 3 weeks to go - what should I do in terms of training?
