How old was Lady Godiva when she took her famous ride?

She was only 17, when she rode naked through Coventry to secure tax reduction for the people!

I can see no mention of her age in the reference. The story in any case is only a legend, and historians have found no connection between the factual Godiva wife of Leofric and the legendary rider. If she was 17 when she rode how old was she when she married Leofric? The ref gives her birth as about 1040, but also says she and her husband founded Coventry monastery in 1043. The whole tale is riddled with inconsistencies.
