How fit do I have to be to do a sportive?
I have about 800 kms under my belt from cycling in July & August. I am doing a night ride from Manchester to Blackpool for the British Heart Foundation on 29/30 September - 52 miles. I spotted the sportive for the Stoke on Trent stage of the Tour of Britain on 23 September and I am tempted but am I fit enough. I'd do the 100 km one. All thoughts & ideas gratefully received.
