Speed king Anthony Porter claimed two separate hat-tricks in round four of the Darley Moor Motorcycle Club Championships.
The Chesterfield rider claimed three race victories, and a runner-up, plus three fastest laps in his class in sweltering conditions at the race circuit.
Porter claimed a victory in the Formula Darley class and in the second race was only pipped at the chequered flag by a quarter of a second.
In one of the races fellow Chesterfield racer Alex Woodhouse was placed a creditable fourth.
Porter proved unbeatable in the Mini Sound of Thunder class when he led all of his laps to claim two impressive victories.
Woodhouse was in third and fourth place in the same class.
Porter now has an extremely commanding lead in both Darley Moor classes.
He has 69 points in the Formula Darley section while his nearest rival has 31.
In the mini Sound of Thunder section Porter has 72 points while Woodhouse is placed third.
Round five of the Darley Moor races take place on Sunday, July 24. Entry for adults is £11 and race action starts at 11.30am.
