The British colt set an extremely fast pace, which had many of the runners struggling at halfway, but Gibert settled Green Forest in third place before making his challenge 400m from the finish. Green Forest accelerated past Sandhurst Prince and quickly went clear of the field to win by three lengths. The Wonder finished strongly to deprive Sandhurst Prince of second place in the final strides. After his win in the Moulin, there was speculation that Green Forest would run in either the Prix de la Foret or the Champion Stakes, but he never raced again. Fustok proposed a $4 million match race between Green Forest and any American-trained colt to be run in two legs at Longchamp and Belmont Park. The connections of Timely Writer expressed some interest, but the match never materialised. In the official International Classification for 1981, Green Forest was rated the best two-year-old in Europe, three pounds ahead of Dewhurst Stakes winner Wind and Wuthering. The independent Timeform organisation reversed the order, rating Wind and Wuthering on 132 and Green Forest on 130. In the International Classification for 1982, Green Forest was the highest-rated French-trained racehorse and the joint-second-best horse in Europe, one pound behind Golden Fleece and equal with Assert and Kalaglow. Timeform named him the best miler of the season, and his rating of 134 made him their equal top-rated horse alongside their "Horse of the Year" Ardross and their "best three-year-old colt" Assert. Green Forest was retired from racing to become a breeding stallion at Jonabell Farm. Despite a promising start to his stud career, he was not a commercial success in USA. By far his most successful offspring was the filly Forest Flower, from his first crop of foals, whose wins included the Irish 1000 Guineas. Other good winners included Made of Gold (Royal Lodge Stakes), Forest Wind (Mill Reef Stakes), and Green Line Express, who won at Group Three level and finished second to Zilzal in the Sussex Stakes. Green Forest was exported to the Dashmesh Stud Farm in Punjab, India in 1995, where he sired the Multiple Classic winner Bonzer in his first Indian crop. Bonzer won 14 races including The Golconda Derby, Gr.1, Golconda 2000 Guineas Gr.2, Deccan Derby, Gr.1, The Bangalore St.Leger Gr.1, The President Of India Gold Cup, Gr.1, andNizam’s Gold Cup Gr.2.
