The clearest pattern is at Musselburgh, where Thunder Wonder is a genuine course specialist. He has won two of his four races there, a 50% return that stands out sharply against his overall 13% win rate. His most recent victory came at Musselburgh on 7 June 2025 in a Class 2 race — one of the better contests — but he has not added to that tally in the six races since, finishing mostly outside the money (8th, 9th, 5th, 3rd, 8th, 4th). Joe Fanning, his most frequent partner, has ridden him in 12 races and won three times together — a 25% win rate that is significantly better than what Thunder Wonder manages in other hands. Their best understanding seems to come when the distance sits between 7 furlongs and a mile, where he has won once from four attempts.
The reality is that Thunder Wonder operates at Class 2 level and tends to struggle there, winning just once in eight races at that grade. He remains an active runner who was last seen just a day ago, but the gap between his Musselburgh masterclass and his current form suggests he may be better suited to easier races at courses where he has already proved himself.
