We're devastated at Jackdaws to hear of the passing of JT, the greatest horseman I've ever known. Our thoughts are with Caroline and family.

Listening to AP McCoy talking so movingly about JT McNamara on @bbc5live. Thinking of his wife Caroline and their three children

Very sad hearing the news about John Thomas McNamara. He was a real fighter & just a decent person. May he rest in peace

If anyone is unsure as to just how good a horseman JT McNamara was, watch his ride on Rith Dubh at the 2002 Festival. It was perfect. RIPJT

RIP JT McNamara. A gifted rider that was tough as teak to the end. This is a lovely tribute video made by @irishp2p. https://t.co/LQc4MyR7z2
