Beckwith, author of Step and Go Together, wrote, "She was as long as a boat and as lean as a hungry leopard ... she had a U-neck and mule ears ... she was lazy, gangly, shiftless ... she was a daisy-eating, scenery-loving, sleepy-eyed and slightly pot-bellied hussy.

The source of the legend was jockey Robert Smart, who told a story 34 years later that the horses were standing at the starting line but Kincsem stood behind them and grazing.

[25] On 22 October, Kincsem stepped up in distance from sprints and won the Kladruber Preis at 1600m in Vienna,[26] beating colts Der Landgraf and Hamburg by 5 lengths.

In the Preis des Jockey-Club (Austrian Derby) on 21 May, her main rival would be Tallós, a colt that had finished second in the Criterion Stakes at Newmarket.

Kincsem earned six victories by walkover and also won a couple of races cantering against her stablemates, who did not challenge her, just running to take the second-place money.

She picked up easy money in the Alamidij (City Prize) in Oedenburg (Sopron) on 29 September where she beat her sole opponent, stablemate Prince Gregoire, by three lengths.

The next day, she entered a race of the same name and the result was stated as a "compromise", meaning Kincsem cantering for the agreed victory over her stablemate Blankenese.

[51][52] After the 1877 season, British racing journalist Mr. Langley from the Morning Post delivered a challenge in the name of Mr. John Fiennes, who owned the Epsom Oaks winner Placida.

Blaskovich accepted the challenge but altered the conditions, suggesting a match for a purse of 50,000 - 500,000 florins (roughly equivalent to €600,000 to €6 million in 2020), at a distance from 2400m to 2800m, held halfway between the two home bases, in either Frankfurt or Baden-Baden.

[54] In the spring, the form of previously undistinguished three-year-old horses can improve dramatically, which posed problems for Kincsem in her first two starts of the season, in the two cheapest races she ran that year.

In a match race in the Államdij over 2400 meters, Kincsem set a moderate pace, easily repulsed a short attack of Prince Giles The First, and won by 5 lengths while giving him a 5 kg advantage.

[62] On 28 May, she repeated last year's victory in the Trial Stakes over a mile, beating Prince Giles The First for the sixth time, in this case by 10 lengths while giving him a 6.5 kg advantage.

The Austrian and Hungarian newspapers enthusiastically reported about another easy victory of the "Wonder Mare", but English turfwriters were shocked by the ride of Madden, well known as hard whip rider in Austria-Hungary and Germany.

He has, I believe, ridden the mare in nearly all her races, and the only wonder to me is that there is anything of her left, as she was spur marked from shoulder to tail; however he kept at it, and, catching Pageant a hundred yards from home, won in a canter.

"[73] English reports later came to Austria-Hungary and the satirical magazine Kikeriki published a cartoon showing a donkey watching the torture of Kincsem with the caption, 'Oh how happy I am that I am not a talent!

[76] The winning prizes in the Goodwood Cup and Molecomb Stakes were £480 and £1,125, converted to 4,800 and 11,250 florins, but Austro-Hungarian and German owners and spectators won much more on bets.

Vadász- és Versenylap published a short message that on 4 August Kincsem made her way to France and ended up in Havre to await her duty in Deauville.

[78] In the Grand Prix de Deauville over 2400 meters on 18 August, Kincsem's main rival was Fontainebleau, winner of the Poule d'Essai des Poulains.

Other starters were Altona at 25/1, the sole German runner Purple at 40/1, and Vsecko-Jedno with no bets because his owner declared he was only running to try a muddy track before starting in the next race.

Blaskovich and Henckel decided to run a second heat, in which many backers turned to Prince Giles The First, a powerfully built colt with a significant weight advantage.

The owner of Altona, János Sztáray, engaged top jockey Tom Busby, who had been beaten by Kincsem many times on Henckel's horses Prince Giles The First, Konotoppa, Blücher and Oroszvar.

Vadász- és Versenylap reported that Kincsem was much calmer than her two restless opponents and looked good but not "fit", having had only three or four true workouts before the race.

[97] On 6 May over 3200 meters, she won by two lengths, beating Austrian Derby and Hungarian St Leger winner Nil Desperandum with her former jockey Madden up.

[98] On 8 May, she won by two lengths over 2400 metres, beating the up-and-coming three-year-old Harry Hall, later winner of Hungarian St Leger, giving him the advantage of 24 kg (53 pounds).

[104][105] After a long break, Kincsem returned to the track on 25 August in Frankfurt, where she rounded the number of victories to 50 in the race supported by her great fan, the Grand Duke of Hesse.

Under jockey Wainwright, she led all the way over 2800 meters and won in a canter by four lengths ahead of leading German three-year-old colt Blue Gown, hard ridden by Madden.

Despite the protests of Wainwright, Hesp replaced him and gave an opportunity to Henckel's skilled jockey Tom Busby, who had been beaten by Kincsem in 32 races before, 17 times as the runner-up.

[136] Kincsem's corpse was sent to the Veterinary institute in Budapest and the autopsy revealed she died of a worm aneurysm,[b] specifically "Thrombosis and embolism caused by colonization of Sclerostomum armatum in the aneurysmal mesenteric artery, which had led to blockage of the artery, edematous, inflammatory and hemorrhagic processes in the intestinal membranes, paralysis of the same and congestion in the mesenteric veins and in the portal vein.

"[144] Taking into account her ability to handle heavy weights and the range of distances over which she was successful, turf historian Richard Sowers wrote that there was "little question that [she] compares favorably with any Thoroughbred in history.

[148][149] In 2021, Tibor Bak (a Swiss-based Hungarian who named his company after the racehorse) showed proposals for an electric hypercar called the Kincsem Hyper-GT, with 54 production models due to be built as a tribute to the 54 races that the horse won.
