I'll be on my exercise bike for two hours each day, starting on November 1st. If you want to see how the ride's going you can visit my route map (https://sift-virtual-cycle.netlify.app), where you can track my progress in real time.

I'm doing this challenge to raise money to support SIFT's amazing health clinics in Nicaragua. Every week Dr Sandra and her team of nurses bring everyday healthcare to rural communities on Ometepe.   It's the kind of health service that we value here in the UK, and it really makes a difference to the lives of the poor. You can browse my photo gallery by clicking on the image above to see Dr Sandra and her team in action.

I'm hoping to raise at least £2,000 through this challenge, which will provide free medicines for two months for everyone who comes to our clinics.
