Time to decide on a replacement challenge

I am going to do a couple of events this summer:

The Long Tour of Bradwell 2011 - Saturday 6th August 2011 - 33 miles/6300 ft of ascent of magnificent (but tough - you have been warned!!) fell running in the Dark and White Peak District. A round of the 2011 Runfurther series (http://www.runfurther.com/)

and:

The 3 Peaks Cyclo-Cross is staged in the Yorkshire Dales National Park every year at the end of September. It is the toughest and biggest Cyclo-Cross event in the UK.

So, an ultra-marathon run that will take about 6 hours and a 5 hour bike ride up and down the Yorkshire 3 Peaks - reckon thats tough enough!
