戒酒七年後，他說儘管 "多次 "感到不確定自己是否能夠完成任務，但完成這項任務是 "了不起的"。
他感謝當地社區在他的挑戰中給予的 "奇妙 "支持，並補充說。"人們真的與它聯繫在一起，這很好。"
A former alcoholic has completed a 70-triathlon challenge for charity to see what he was "capable of".
Having been sober for seven years, he said it was "amazing" to complete the task despite "many" times feeling unsure he would be able to.
He had been intending to achieve a Guinness World Record for 70 consecutive 70.3-mile triathlons, but due to the enforced break, he aimed instead for a world record for 35 consecutive 70.3-mile triathlons, and also the record for the most of that distance in a year.
"The whole final day was so surreal," he said. "It was absolutely amazing, I was blown away."
He thanked the local community for its "fantastic" support during his challenge, adding: "People have really connected with it and it has been great."
Mr Stone said he had battled mental health issues and addiction for several years and could not have imagined doing multiple triathlons when he felt at his worst.
Hearing from addicts or people in recovery during his tasks had also been "fantastic", he said.
In total, he said he had raised more than £12,000 towards mental health and addiction charities.
