Speed: No Limits was a steel roller coaster at Oakwood Theme Park in Pembrokeshire, Wales. It was manufactured by Gerstlauer and was the first Euro-Fighter model to be installed in the United Kingdom. The ride was installed by Ride Entertainment Group. It opened on 13 April 2006, and operated until 3 November 2024. It has since been relocated to Walygator Sud-Ouest in Agen, France.
Its lift hill was 35 metres (115 ft), and it featured top speeds of 95 km/h (59 mph). The ride had two inversions, and exerted a maximum of 4.5 Gs on riders.
It featured a vertical chain lift hill and a 97ð first drop. This drop gave it a five-way tie for the record of steepest roller coaster drop between itself, Rage, Fahrenheit, SpongeBob SquarePants Rock Bottom Plunge, Vild-Svinet and Typhoon, until Steel Hawg took the record in 2008.
The ride had four trains, each consisting of two rows with four across seating, for a total of eight riders per train. The trains featured over-the-shoulder restraints.
Upon dispatch from the station, the train made a right-hand turn before ascending the 35-metre (115 ft) vertical chain lift hill. This was followed by a 34-metre (110 ft) beyond-vertical first drop at an angle of 97ð, reaching a top speed of 95 km/h (59 mph). The train then traversed a camelback hill and entered an overbanked turn at 110ð, which led into a vertical loop before rising into a block brake section. Following a small dip, the train navigated a heartline roll, then turned left with a slight incline and entered a double helix that led into the final brake run. The train completed the circuit with a right-hand turn returning to the station. The full ride lasted approximately one minute and 30 seconds.
