At Cambridge, he excelled as a rower.
Muttle, as he was called at the varsity and later in life, rowed for Cambridge in five successive Boat Races between 1886 and 1890, losing only once in 1890.
Race of 1886 As a freshman, Muttlebury made his first appearance in the
1886 Boat Race in the six seat of the Cambridge crew. The prospects of a Cambridge victory were initially poor, with only two returning Blues, Symonds, and the President, Pitman. However,
Steve Fairbairn was persuaded to return. With the addition of Muttlebury it was considered "the crew could not be but fast; yet the betting was very even when the fateful day arrived." That year,
Hammersmith Bridge was under repair. This gave only a narrow space between the boats should the two crews shoot the bridge abreast. Oxford won the toss and chose the Surrey side. Cambridge went out to an early lead of half a length at Craven Cottage, but Oxford slowly clawed this back by the Soap-works. The two crews were level at Hammersmith Bridge, but avoided a collision. After Hammersmith Bridge, rough water was encountered, and Oxford moved out to a lead of more than two lengths. However, Cambridge made a sustained effort from
Barnes Bridge, and won by two-thirds of a length in a time of 22 minutes 30 seconds.
Race of 1887 After winning the Boat Race of 1886, and the success of Cambridge College crews at Henley the same year, it was considered natural that Cambridge should put on a very fine crew for the
Boat Race in 1887. Muttlebury was one of four returning Blues, including
Steve Fairbairn and President, C.J. Bristowe at stroke. Muttlebury again rowed at six. However, Oxford had the services of the freshman
G. Nickalls, and five time Boat Race oarsman,
D. H. McClean. As a consequence, the crews recorded comparable times in trials at Putney, and the race was looked upon as very open. Cambridge won the toss and chose the Surrey station, and with a good turn of speed were ahead by a length and a half at the Crab Tree. However, in spite of the bend being against them, Oxford closed the gap such that there was no daylight between the crews at Hammersmith Bridge. After shooting the bridge, rough water was encountered, and Cambridge took the advantage of the sheltered station to take a lead of three lengths. But at Duke's Meadow the shelter favoured Oxford, who began to move up very quickly on Cambridge, and at Barnes Bridge they had all but eliminated Cambridge's lead. They were drawing up very quickly when the oar of the Oxford seven man, Douglas McLean, broke in the gate. Reduced to rowing with only seven men, Oxford were unable to complete their challenge, and Cambridge won a fortunate race by two and a half lengths in 20 minutes 52 seconds.
Race of 1888 In 1888, Muttlebury became the President of the
Cambridge University Boat Club, a post he held for three successive terms. Oxford should have produced a good crew, with Guy Nickalls, W.F.C. Holland, and H.R. Parker returning to row, George Drinkwater noted that they "did not develop into a good crew and were never looked on as possible winners", while Cambridge "had a surplus of excellent material". Cambridge won the toss, and chose the Surrey station, extracting a lead of six lengths by Hammersmith Bridge, and eventually won by seven lengths in a time of 20 minutes 48 seconds.
Race of 1889 Stanley was President for C.U.B.C in his second year for the
1889 Boat Race. With all eight of the previous year's Blue Boat available, he chose an identical line-up, other than the coxswain. This was the only time in Boat Race history such a selection occurred. However, his decision attracted not inconsiderable criticism. The official centenary history of the Boat Race noted: Once again Cambridge won the toss, and chose the Surrey station. They had managed to achieve a lead of a length and a half by Hammersmith Bridge and eventually won by three lengths, in a time of 20 minutes 14 seconds.
Race of 1890 The
1890 Boat Race marked Muttlebury's third and final year as Cambridge President. He started off at a disadvantage due to his being the only Old
Blue in residence at the beginning of training. The Boat Race historian
Dickie Burnell would note that "Muttlebury had to pay the price of having rowed in 1889 the same crew which had represented Cambridge in 1888," although there was possibly little between the crews. The Oxford crew of Vivian and Guy Nickalls,
Lord Ampthill,
W. A. L. Fletcher and R.R.P. Rowe had more experience, and after a tough battle, triumphed by one length to hand Muttlebury his first and only Boat race defeat. ==Other sporting endeavours==
