Well this should be “fun”.
Take the spring classics…
Milan-San Remo – 6,260 feet (1,908 meters)
Tour of Flanders – 5,709 feet (1,740 meters)
Paris-Roubaix – 3,259 feet (993 meters)
Liège–Bastogne–Liège – 10,883 feet (3,317 meters)
Amstel Gold – 8,993 feet (2,741 meters)
…add up the total cumulative climbing…35,104 feet
… then TREBLE it… 105,312 feet
Now go & ride at least that much between March 15th and April 30th.
Yikes! Needless to say, I already have a spreadsheet with proposed rides & associated climbing figures laid out. I’ve missed the first few days but I *think* it’s just about doable. I’m planning a Trans Cambrian Way end to end in 12hrs on April 21st, which will help (15k feet there). I need to aim for about 10,000 on each Saturday ride (that’s about double what I do at the moment, but I’m ready to step it up anyway). Weekday rides can pretty much stay the same, just need to ensure around 1k ft per Monday morning, Tuesday and Wed lunchtime, then at least 2k ft on Thursday evenings on the Chilts, and maintain the approx 1500ft on Tuesday evening social rides. I think the turbo will be out of the equation for a few weeks 
As I’ve missed the first few days of the challenge, I’m only starting from 6508ft from this morning, but I think I can make up for that. After all, a free water bottle is a free water bottle, isn’t it!
You need to start working on getting sponsorship for things like this. Can I suggest that you talk to Penny about doing the Trans Cambrian Way as an Action for Children sponsored event? Collecting sponsorship moneies these days could not be easier with Virgin Money Giving website. It even links with bloging sites too.
heh cheers matey, though there are a lot of people out there doing far more than me so I’d only want to seek sponsorship for the really big stuff. Perhaps if I end up having a go at the TCW double…that would be a monster.
