The 16-year-old, who is also currently leading the Formula MRF 1600 category in the MMSC National Racing Championship, won a close battle for third place in the second race of the weekend. Combined with seventh and ninth positions in the other two races, Reddy keeps sixth place in the championship.
Reddy's plan to get in some testing on the challenging Donington track was scuppered by wet weather, meaning his first laps in the dry at the historic venue with his MGR Motorsport machine came in qualifying.
Race two featured a fierce battle with title contender and eventual winner Matteo Ferrer. Reddy had moved up to third by passing Canadian Patrick Dussault, but then came under attack from Ferrer, who got by into the first corner. The India then repassed the Italian with a brave move into the Old Hairpin - which despite its name is the fastest corner on the track - and Ferrer went sailing off the track at the next corner. Reddy then held off a renewed attack from Dussault for his maiden podium in the UK.
His manager, Formula MRF 2000 champion Rupert Svendsen-Cook, added: "Tarun made a big step forward from Rockingham, which is all you can ask for. It was his best qualifying so far, and his best race finish - and to finish on the podium is a massive achievement. He drove a very hard race, but very fair as well, and that's great at such an early stage in his career."
