Turbo Trainer Advice

Bikecalculator, with a gradient of 7% and a distance of 21km gives a requirement for 240 watts to hit 110 mins for a 90kg rider on a 7kg bike.

I'd be surprised if you couldn't hold that SF.

Look up thread at my calcs.

Bear in mind that I use alu nips, and latex inners. So I'm uddles more efficient.

To be blunt, but fair at 90kg I'd worry nowt about training and more about losing weight.

As you are talking about riding up hills.

86Kg, and 5'7". So you're right.

But I have a 2 day rugby tournament next weekend, and I've evaluated that being an underweight rugby forward is more painful than being an overweight cyclist.

That said. I will look to get down as much as possible inbetween.
