Farah becomes the first athlete to win the Great North Run four times in a row, although he is on equal terms with Kenya's Benson Masya, who was champion four times in the 1990s.
Kenya's Mary Keitany won the elite women's with the third fastest time in its history as Vivian Cheruiyot came second and fellow countrywoman Caroline Kipkirui came third.
For Masa, however, there was an unexpected bonus at the end of the course as her boyfriend Robertson took the opportunity to propose to her - and was accepted.
London Marathon victor Mary Keitany of Kenya surged to her third victory in the women's race in 1hr:05min.59sec.
Farah told the BBC after his season-concluding race: "That was really, really tough".
"I think it's down to a lack of training!"
It will be Farah's third London Marathon after he took part in the event in 2013 and 2014.
"I'm sore everywhere- I've never been this sore".
"I can't wait to start a new adventure racing on the roads in 2018, starting with the world's greatest marathon", he said.
"With four miles to go, I was hanging on and gritting my teeth".
"When I chose to concentrate exclusively on the roads from 2018 I knew that I wanted this to be my first marathon".
With a towel wrapped around his shoulders and just a few paces over the line, Robertson got down one knee when his partner approached to congratulate him.
Laura, originally from Peterlee, County Durham, who is now living in Delaware, America, said: 'When she popped the question I had no idea the ceremony would be at the next year's Great North Run.
The New Zealander finished second in the half-marathon after pushing British Olympic hero Mo Farah to his fourth consecutive title.
"I'm so pleased with how the season has gone".
