Thank you for all your submissions today - more than we could possibly use and more inspirational than I could put into words.
Have a look at #bbcathletics on Twitter and Instagram to check them out and give some of those involved some love and, if you can, some currency for their charities of choice.
The London Marathon will hopefully be back on the 4 October, but the 2.6 Challenge is doing a grand job of filling the void in our sporting lives and the shortfall in charity coffers.
We bring you an update from Dr Adam Revill (see 11:46) - an intensive care consultant who contracted coronavirus, recovered and was running a backgarden marathon for Rowcroft Hospice today.
He is finished in a stonking 3 hours and 38 minutes on a course that included more than 2,300ft of elevation gain.
His sister in the Midlands won the sibling bragging rights, getting done in 3:24.
American Dick Beardsley shared the inaugural men's London Marathon title with Norway's Inge Simonsen after they crossed the line together in two hours 11 minutes and 48 seconds.
Britain's Joyce Smith won the women's race in 2:29.57.
And it is pretty warm out there in most part of the country. So, these three alpaca are taking a break after reaching lap number 20 of their 26 lap challenge in aid of Vauxhall City Farm.
The name of the challenge? Alpaca Laps Now. Which is certainly the pun of the day.

Two years ago, David Weir, London born and bred, won an unprecedented eighth London Marathon title, keeping Marcel Hug and Daniel Romanchuk at bay in a high-speed sprint finish.
The top picture shows runners from the 2016 London Marathon passing the Old Royal Naval College in Greenwich and the bottom one shows a solitary jogger out on the streets all by themselves this morning.
"The marathon is really a metaphor for life. And I think people understand that even more so once they experience it,” she said.
“You never know what’s around the next bend. Are you gonna hit the wall? Are you gonna feel good the entire way? Are you gonna have miles that are really taxing and challenging?
“Either way, each runner dictates their own course of action among a much larger population all seeking the same goal. It is such an individual, but collective event.”

'The marathon is a metaphor for life'
Joan Benoit Samuelson - the first woman to win Olympic marathon gold - was due to be running in London today.
It would have meant the 62-year-old had run marathons in six consecutive decades after her first in Boston in 1979.
She told BBC Sport what the marathon distance means to her.
"The marathon is really a metaphor for life. And I think people understand that even more so once they experience it,” she said.
“You never know what’s around the next bend. Are you gonna hit the wall? Are you gonna feel good the entire way? Are you gonna have miles that are really taxing and challenging?
“Either way, each runner dictates their own course of action among a much larger population all seeking the same goal. It is such an individual, but collective event.”
Super effort!
Why do one challenge when you can do 26?!
Wow - there's some wonderful lockdown challenges on your list, Fliss.
Not sure I've even got 26 pairs of shoes for the stair challenge!
Making a 26-shaped cake sounds great fun.

Eliud Kipchoge makes the rest of humanity look like they are running through golden syrup doesn't he?
The Kenyan great jigged down the Mall last year to victory in 2:02:37 - then the second-fastest time in history.
