1998: two-year-old season Mujahid began his racing career in a six
furlong novice race (for horses with no more than one previous win) at
Newmarket Racecourse on 8 July and started the
6/1 second favourite behind the odds-on favourite Belasco. After starting slowly, Mujahid began to make progress in the last quarter mile, took the lead from Compatriot inside the final furlong and held off a late challenge from Belasco to win by a head. Two weeks later at
Salisbury Racecourse Mujahid started 2/5 favourite for the Trinity Stakes against two opponents. After tracking the leader Boomerang Blade, Mujahid took the lead at half way and drew away to win "very easily" by six
lengths from Sunny Fact. The colt was then stepped up in class for the
Group Two Gimcrack Stakes at
York Racecourse on 19 August and was made the 13/8 favourite ahead of Bertolini (winner of the
July Stakes) and Rosselli (
Norfolk Stakes). After tracking the leaders, Mujahid struggled to obtain a clear run in the straight and finished fifth of the eight runners behind Josr Algarhoud, Sailing Shoes, Thunder Dragon and Bertolini. John Dunlop later said that the colt had been unsuited by the
firm ground. Despite his defeat at York, Mujahid was moved up in class and distance to contest Britain's most prestigious race for two-year-olds, the Group One Dewhurst Stakes over seven furlongs at Newmarket on 17 October. The joint-favourites were
Stravinsky and Enrique (
Somerville Tattersall Stakes) whilst Mujahid started a 25/1 outsider. The other four runners were
Lujain, Auction House (
Champagne Stakes), Raise A Grand (
Solario Stakes) and the French challenger Indian Danehill. Mujahid tracked the leader Auction House but appeared outpaced when Enrique went to the front two furlongs out. He rallied when switched to the right by Richard Hills, took the lead inside the final furlong and won by two lengths and a neck from Auction House and Stravinsky. When interviewed after the race John Dunlop told journalists "You pundits always get it wrong" but admitted that he did not think that Mujahid would be "good enough against these cracks".
1999: three-year-old season On his first appearance as a three-year-old Mujahid started odds-on favourite for the
Craven Stakes (a major trial race for the
2000 Guineas) over one mile at Newmarket on 15 April. He ran unaccountably badly and finished fifth of the seven runners behind
Compton Admiral. Mujahid's groom Steve Gill later commented "We were gobsmacked after Newmarket. We couldn't find anything wrong with him and everyone was gutted. The guv'nor said that, after 33 years of training, he had never been so surprised by a result". Despite his poor performance Mujahid contested the 2000 Guineas on 1 May and started the 9/1 fifth choice in the betting behind
Orpen, Enrique, Auction House and
Commander Collins. As the Rowley Mile course was being redeveloped the race was run on the July, or Summer course. After tracking the leaders in the early stages he moved up to dispute the lead two furlongs out and kept on at the same pace to finish third behind
Island Sands and Enrique. Two weeks later the colt was sent to France for the
Poule d'Essai des Poulains over 1600 metres at
Longchamp Racecourse and finished fifth behind
Sendawar. In the
St James's Palace Stakes at
Royal Ascot in June the colt finished seventh behind Sendawar, who won by one and a quarter lengths from
Aljabr. After a break of over four months, Mujahid returned in the Group Two
Challenge Stakes over seven furlongs at Newmarket on 16 October and finished fourth behind Susu, Lend A Hand and Josr Algharoud. On his final appearance of the season Mujahid contested the
James Seymour Stakes over ten furlongs at Newmarket and finished second by a length to Little Rock.
2000: four-year-old season Mujahid remained in training as a four-year-old, beginning his third season in the
Earl of Sefton Stakes over nine furlongs at Newmarket on 19 April. He finished third of the eleven runners behind Indian Lodge and Fairy Godmother. Nine days later Mujahid was brought back in distance for the
Sandown Mile and finished fifth behind Indian Lodge. ==Assessment==
