They included Bath GP Dr Sam Parsons, running her first London marathon, who finished in four hours five minutes. At the time of writing she had raised more than £670 for the Kidney Wales Foundation.
Sam said: ‘It was an amazing experience, I started to struggle from mile 21 but the crowds were so encouraging - they kept me going. Crossing over Tower Bridge at almost halfway was my favourite point - that memory will stay with me forever! It was just fantastic.’
East London GP Dr Stuart Bingham completed his 22nd consecutive London marathon in three hours 51 minutes and has so far raised £950 for Macmillan Cancer Support. To see a picture of Dr Bingham in the race and to find out more about how he did.
The quickest GP finisher was east Surrey GP Dr Joe McGilligan (three hours 41) who has so far raised £545 for Sense. He said: '‘It was tough but really enjoyable. The crowds were a fantastic support and I am pleased with my time which is the same as I did in New York in 2010.’
Former GP columnist Dr Mary Lowth finished in five hours 29 minutes and has so far raised £1,644 for Cancer Research UK.
Dr Lowth said: 'It was a wonderful experience. My predictions did come true - I was passed by the chicken at the 18-mile point. I ran most of the way with six people dressed as rhinos. The high spots on the costume front were the aptly named Testicle Man who was raising money to combat testicular cancer and who had a somewhat distorted idea of anatomical proportion and the ostrich whose costume slipped upwards at the excitement of finishing and revealed he was wearing nothing underneath.
'My own performance started well. The first 13 miles were great - I did them in 2 hours 20, which I was pleased with as it included a 12-minute queue for the loo. Unfortunately some twinges (knees, ankles, feet, groin) started at 13 miles and by 18 miles were so severe I had to slow down. My second half took me an hour longer than my first half - total time 5 hrs 29. Now I have more black toenails than white ones. I look like Jack Sparrow, only less lively.
'Plusses - the atmosphere, the crowds, the setting, crossing Tower Bridge, the start, the finish, the sense of having done it, Cancer Research team cheering us on, not actually being tired, racing a rhino to the finish, seeing Mike Fitchett and family waving me on in the Isle of Dogs, putting my iPod on shuffle and having What a Beautiful Day blare out of it at top volume just as I was feeling particularly crippled.
'The minuses - the possession of aged feet. Definitely.'
'Thank you so much for all your generous sponsorship.'
Suffolk GP trainer Dr Jenny Morrison finished in four hours 49 minutes and has so far raised over £2,070 for Age UK.
She said: ‘What an amazing experience - very tough especially after the 20-mile mark but spurred on by so many people from the crowd offering support and sustenance. Even the last bit where the banner comments ‘only 385 yds to go’ -the London Pride bottle; giraffe; fairy and Chris Evans and myself all trotting in to each complete our own personal goals.
'The amount of support has been incredible from family, friends, staff and especially patients and my thanks to the Age UK members who prepared me so well and even went to support but did not manage to catch a glimpse of me in that incredible number of runners.Thanks to all my target has been overtaken and now looks to be over £2,300.
‘I must thank the large number of people, many volunteers, who make the day go so smoothly.Did I say never again ?’
Finally, running for Arthritis Research UK were Dr Johan Bryan (four hours 51 minutes) and Dr Harriet Edwards (six hours two minutes) who both have arthritis. Dr Byran who is running 12 marathons in 12 months has so far raised over £2,430 and Dr Edwards over £2,400.
Dr Byran said: '‘I am privileged to have completed my fourth out of 12 marathons this year in aid of Arthritis Research UK. The London marathon is special not only because it’s my home town, but because it was the first marathon I completed seven years ago in support of the charity.
‘I was a vulnerable 18 year-old, that felt powerless to change his circumstances. I hope by completing this challenge more people will feel inspired and empowered to overcome their adversities. Part of the solution is to fund further projects and research into novel treatments that will help us turn more sufferers into survivors.
Every donation really does count. I am grateful to everyone that has shown so much support to me and Arthritis Research UK for the first four marathons of 2015 and continue to do so as I plan to run the next eight marathons in the hope of raising £12,000.’
Dr Edwards said: 'The day was fantastic and it was really nice having Arthritis Research UK cheering at three different points on the course. I had so much support from beginning to end and I felt part of a team with a real sense of community. It was great to run for a cause that means so much to me personally.
‘I would like to thank all my friends and family for their kind donations online, for sharing and enabling me to reach my target for Arthritis Research UK. All the money raised will help the charity continue to help to raise awareness and fund key research into the causes, treatment and cure for arthritis.’
