Dunwich Dynamo 2008

I'm not surprised you fear them, that's still 74.6 GI

I know some people gear UP for dunwich cos it's "flat" but after 6 hours anything can feel like a grind, hence my get out of jail (hopefully) 67

I used to run 44/17 which is 69, a great all round gear. it's not a time trial
It's 72.7
We'll have none of your dirty 47 / 17 * 27 mathematics here.
