Nigel Keer was wearing nothing but a backpack, boots and a baseball cap when he met a woman walking her dog on October 2 last year.
Off-duty police officer PC Mark Buxton, who was out running, arrested Mr Keer after spotting the woman who looked distressed.
PC Buxton told Leeds Magistrates' Court: 'She had a disgusted frown across her face.
'I saw her turning around, I could tell she was upset about something.'
The officer approached the naked rambler and ordered him to get dressed, which he did.
PC Buxton added: 'I was so shocked and surprised - and to some degree alarmed - by what I had just seen.'
Mr Kerr claimed the woman referred to by the police officer didn't exist and said he'd kept score of the number of positive and negative reactions he'd received during his stroll that day, with a score of 15-0 in his favour.
However, despite his protests, he was found guilty of a public order offence.
Judge Christopher Darnton said: 'I do accept that Mr Keer is a naturist but I note with some interest that he would not walk with his clothes off in the city centre of Leeds.
'On this occasion a lady was clearly distressed by what she had seen going on.'
