This section shows how the facilities at The Valley were upgraded in preparation for professional racing licensed by the Greyhound Board of Great Britain (GBGB), which began in November 2023.
The new outside hare system, which was delivered in mid-August 2022, finally became operational in March 2023. The former hare was a Sumner system that operated on the inside of the track via a rather complex (and noisy) array of pulleys and rollers driven by a large aluminium wheel housed near the finishing line. This has been replaced by a completely different Swaffam McGee mechanism that runs (in almost complete silence) on a rail sunk at ground level around the outside of the circuit with much of the drive mechanism concealed underground. The rail arrived in sections that were carefully welded together and set into more than 400 metres of specially constructed concrete footings to ensure that the internal cable runs smoothly without snagging.
The hare rail runs in front of the old starting traps so new boxes arrived that can be swung on and off the track by powerful hoists. They were installed further up the home and back straights. A new inside safety rail, made by specialist manufacturer Barriers International, was also completed. Much of it was installed by hand by new track owner Dave Barclay and his son Lee – who oversees stadium management at Harlow – who were soaked to the skin after selecting one of the wettest weeks of the year for the operation.
The new starting positions shortened the run-ups but the finishing line was moved nearer to the first bend, so the racing distances are not significantly shorter than before. The main standard, four-bend distance is now 460 metres (previously 475 metres). The two-bend sprint distance is 260 metres (previously 286 metres) with the six-bend stayers course at 645 metres (previously 665 metres).
The construction of a new building to accommodate a professional on-site veterinary surgery plus a new judges’ box was completed in early 2023, but this was just the first of a succession of new buildings that sprung up on the site. Planning permission was secured to erect a new two-tier building on the currently-vacant platform south of the starting traps on the home straight. The lower tier will eventually accommodate an additional bar area with a separate function room above.
At the other end of the spectators’ lounge, the area currently occupied by the track bookmakers was extended into the former paddock. The old stewards’ building was gutted and completely rewired and the vacant space was extended further up the home straight to create a spacious catering area.
Whereas many existing greyhound stadia have had to install camera facilities as something of an after-thought, The Valley’s judges’ box features a purpose-built, glass-fronted camera platform right on the new finishing line and the stadium’s floodlights will eventually be upgraded to improve broadcast picture quality. During the stadium’s days as an independent track, races were hand-timed using a stopwatch. Now, a photo-finish system has been put in, along with an automatic timing system, which means that all greyhounds’ performances are now measured to a hundredth of a second as soon as they cross the line. The system was personally wired by Irish-based Geordie Gavin Smith who is acknowledged as the world’s leading expert on automated trap-opening systems. Work was completed on the largest new trackside structure, the racing kennels, which stretch from the first bend all the way to the existing trainers’ toilet facilities. The kennel blocks were finished and a state-of-the-art air conditioning system installed.
A new building to house the stadium’s tractors and other equipment is situated on the crown of the first bend.
The extensions enable the stadium to accommodate hundreds of spectators in comfort indoors with additional standing room still available around the perimeter wall. All of the new buildings were cladded and trimmed to match the spectators’ lounge to give the development a clean and uniform external appearance.
Planning permission was then secured for an additional development on the other side of the spectators’ car park. The dilapidated former Tredomen FC social club was bought by Malcolm Tams in 2021. Work was undertaken to gut the building ahead of its refurbishment and repurposing as extensive kennel complexes for two attached trainers who are now employed to augment the supply of runners for the track’s professional graded races.
Malcolm Tams, who owned the Valley Greyhound Stadium for more than a decade, was retained as a consultant to organise and manage the stadium development. 
He ensured that much of the work was carried out by local people who are also very familiar figures at the Valley Greyhound Stadium. Father and son team Charlie and Christian Darch – who have owned some of the Valley’s top greyhounds – were in charge of much of the construction work and they even roped in the temporary assistance of another Valley regular, Charelle Jones. Malcolm’s brother-in-law and business partner, Steve Miles – who used to help out at the gate on race nights – put his decades of experience as an electrical contractor to good use by wiring all the new buildings.
After buying the Valley Greyhound Stadium, Dave Barclay immediately leased the stadium back to former-owner Malcolm Tams so that it could continue to operate as an independent ‘flapping’ track until a Greyhound Board of Great Britain licence was applied for. A number of owners invested in new greyhounds and, together with a steady flow of locally-bred pups, they ensured that the racing strength retained its depth. The extensive construction work to upgrade the stadium’s facilities disrupted greyhound racing at times, but ‘flapping’ meetings were able to continue right up to the time when The Valley applied for a GBGB licence. The last ‘flapping’ meeting took place at the end of July 2023. The Valley Greyhound Stadium then worked with existing owners to help them to register their greyhounds with suitable GBGB-licensed trainers ahead of the start of professional racing at the track later in 2023. A number of former amateur ‘flappers’ applied for professional trainers’ licences and now run greyhounds in GBGB-licensed races at the Valley. Other local people became track officials, staff and kennel hands. In total, nearly twenty former ‘flappers’ – who used to race greyhounds at The Valley as an unpaid hobby – are now employed at the track on race days in one capacity or another.
