The TT returns in 2022 after a two-year absence following the COVID-19 pandemic, with action starting last Sunday with the first official qualifying sessions.
Racing continued on Monday, Tuesday and Wednesday, with tonight’s race consisting of a lap for Sidecars, followed by a Superbike, Superstock and Supersport session.
Just after 8 p.m. local time, the session was red flagged for an incident on the super-fast Ballagarey section of the 37.75-mile mountain course.
The following Sidecar session was canceled following the incident, with TT organizers announcing around 10:30 p.m. Wednesday evening that Welsh rider Purslow had died as a result of the crash.
Purslow was contesting his second TT having made his debut in 2017, following victories on the Manx Grand Prix course.
A statement from the TT organizers read: “The Isle of Man TT Races regrets to confirm that Mark Purslow, 29, of Llanon, Ceredigion was killed in an incident during the fourth qualifying session of the TT Races of the Isle of Man 2022.
“The accident happened in Ballagarey, before the fourth kilometer, during his third lap of the session.
“Mark made his first appearance in the TT Mountain Course at the 2015 Manx Grand Prix where he won the lightweight race on his debut. He graduated from the Isle of Man TT races in 2017, competing in the Supersport classes and Lightweight – 2022 was his second TT.
“Mark was also an experienced classic rider, competing in the Classic TT in 2016, 2018 and 2019, with a best result of 14th in the 2019 Junior Classic TT.
“Mark had set his fastest lap of the TT Mountain Course at 120.86mph earlier in the session, with his first lap exceeding 120mph.
“The Isle of Man TT Races sends its deepest sympathy to Mark’s family, friends and loved ones.”
On Tuesday evening, another rider, Dave Moffitt, was airlifted to hospital in Liverpool after an accident during the lightweight class qualifying session.
He is said to be in “serious but stable condition”.
