Hendrick Ramaala and Berhane Adere took the spoils after hard-fought races in Newcastle's Great North Run.

Impressive South African Ramaala pulled away from Dejene Berhanu and Dathan Ritzenhein to win the men's race in one hour, one minute and three seconds.
And Ethiopian Adere shrugged off Susan Chepkemi and Benita Johnson in the last 500m to clock 1:10.01 in the women's.
Britain's Jo Pavey turned in a plucky performance on her half-marathon debut to finish fourth.
She was in contention with the lead trio coming into the last mile, but hit the wall and collapsed to the ground exhausted just after crossing the finish line.
"I'm finding it hard to recover," said a still-shaken Pavey more than an hour later.
"I'm disappointed because I was enjoying the race but with six minutes to go I felt really weird and with 800m to go I felt really delirious and couldn't get to the line."
"I'd love to try again and get some advice from Paula (Radcliffe). I'd like to give it another go but I need some answers."
Kenyan Chepkemi out-kicked Australian Johnson to claim second spot.
But the race belonged to Adere, who won at the fifth time of asking after finishing second to Paula Radcliffe three years ago, when she ran a world record 1:05.40.
Ramaala, 34, won the Great North Run for the third time, after finishing third last year.
"It was the slowest of my three victories but it was much easier than in 2003 when I had to go all out in the finishing straight," he said.
"It was kind of a tactical race - I was kind of saving myself for the finish because I know Berhanu has a finish. I know at his best he can fly."
The men's wheelchair race was won by Kurt Fearnley, while Canada's Diane Roy won the women's event.
Blackpool's Shelly Woods could only manage second place and Paralympic gold medallist Dame Tanni Grey-Thompson finished fifth.
