Howard Johnson feels he would lack the confidence to return to the training ranks after four and a half years away from racing.
Based in County Durham, Johnson is free to reapply for a training licence after a four-year suspension for breaching welfare and horse medication rules ended last August.
There had been speculation the 62-year-old could be on the verge of coming out of retirement when he was spotted at Sedgefield on Sunday - his first visit to a racecourse since the completion of his ban.
But Johnson, best known for his handling of three-times World Hurdle winner Inglis Drever, has no intention of making what would be a dramatic comeback.
"I'm not going to bother," he told Press Association Sport.
"I went to Sedgefield at the weekend and there was no shortage of people enjoying themselves, but it's gone a bit quiet in the north in terms of good horses.
"It's strange what's going on in the north, but you need good, strong owners behind you and I don't think many of the trainers up here have that.
"There's been a bit of contact with a few of my old owners wanting me to start again, but after five years out, I wouldn't feel confident."
Inglis Drever's owner Graham Wylie is now enjoying great success with Ireland's dominant force Willie Mullins - an alliance Johnson claims to have brokered.
"It was me who told Graham to send all of his horses to Willie Mullins," said the former trainer.
"They were all going to Paul's (Nicholls) but I told Graham that Willie was a top-class trainer going places and now look at him.
"Graham is very happy with where he is, and good for him,"
Johnson will not return to training, choosing instead to focus on his farming operation in Crook, near Durham, but he has been a keen follower of the staying hurdle division after the gifted Thistlecrack further bolstered his World Hurdle claims at Cheltenham last Saturday.
Johnson said: "That horse is relentless, isn't he? Kayf Tara is his stallion, and his horses always improve with age and this is one hell of an improver.
"All credit to Colin Tizzard, he probably has the best three-mile hurdler and the best three-mile staying chaser (Cue Card) in the country."
When asked how Inglis Drever in his prime would get on against Thistlecrack, Johnson said: "T histlecrack has everything, and Drever was a harder ride than he was.
"Then again, our boy won three (World Hurdles) so he's got a long way to go just yet."
