From running events, to TV specials (Did you see the Davina programme - incredible!), thousands of people have been finding ways to raise money for people in the UK and overseas.
I was invited along on the final day of fundraising, so was up at the crack of dawn and headed over to the Olympic Park for the Sainsburys Sport Relief Games.
Anyone could take part in the fundraising. There was running, cycling or swimming events taking place in the Olympic arenas and everyone could raise as much as they could for the cause.
I was touching up on my spectator skills instead of taking part, and had already text FIVE to 70510 (or TEN if you want to donate £10) to add my donation to the increasing amount! You can also donate here.
We headed over to the Veldrome, where the team had set off on a 25 mile cycle around London!
Anyone was able take part in a 3 mile, 25 or 50 mile bike ride, and with the team out for a couple of hours we were given a guided tour of the Velodrome.
Walking through the corridors where the competitors of London 2012 got pumped up ready to compete, we were whisked down some stairs and followed the sign to where numerous gold medals were won.
Welcome to the center of the cycling track.
You can tell that the atmosphere here in the Olympics was mind-blowing.
6000 people cheering on Team GB to seven medals as they flew around the track.
You can get lost imagining how it was, reliving the events shown on TV and wondering what was going through the athletes minds whilst they waited in the centre before they raced.
I was absolutely hooked to the Olympics. I am a sprinter, my dad is a triathlete, so I was glued to the TV to watch Team GB compete in here. To be stood here 18 months later was amazing.
With a couple of bikes on the side, we jumped on to have a little ride around the centre for our own little version of competition!
The bikes are so light that you could lift them with a single finger.
Racing over, and still in awe of the venue, we walked around the steep track and headed back out to the front to cheer the cyclists on!
Although Liv had other idea's and surprised me.
As well as your usual racing and cycling bikes, people were riding the route on unicycles, dressed in onsies or as bumble bees, or as I am about to learn...
A penny farthing.
Trust me, it is harder than you think but worth the laughter as I tried to cycle without any help!
Whilst the cyclists are out taking part in the course, others were taking part in the Mile.
A one mile run around the Olympic Park, with the entry fee going to Sport Relief.
That entry fee, along with all the other money raised, can help better peoples lives.
Did you know that £50 can provide a hot meal to 50 children who are living in extreme poverty in the UK?
Five pounds, which is the same price as I pay for one drink on a night out, is such a small amount but can make such a huge difference.
This is why everyone is taking part in activities to help causes both in the UK and abroad.
Every time I come to the Olympic park, there is this atmosphere that you don't find anywhere else in London.
Thousands of people had turned out to take part, cheer on, and in this case help raise money for a good cause, which is exactly what the team had done when they arrived back from their 25 mile cycle.
Plus, one of the bikes is going to be auctioned off for charity too.
Photo's done, we headed off out into the park over to the Aquatic centre for the Swimathon.
The great thing about all of the venues is that they are opening to the public. You will be able to learn to cycle round the Velodrome, or the BMX track. The Olympic stadium is being refurbished ready for West Ham to take residency too.
Even better, you will be able to swim here.
Welcome to the Aquatics centre.
The homeplace of Tom Daley's bronze medal in London 2012.
Today, the home of the public taking part in a 1.5, 2.5 or 5km swim to help raise money for Sport Relief. Again, the entrance fee goes towards the total raised and you get to swim in this amazing venue.
We sat and watched some of the swimmers go up and down, and cheered on those who were on their last lap of their distance.
The aquatic centre is open now and you can find out more info here about going swimming there! It i an amazing venue, along with the Velodrome and Copper Box, and ensures the legacy of London 2012 continues.
If you haven't yet, then there is also still time to donate to Sport Relief. It's only a fiver and would make the world of difference to someone who needs it!
Well done to everyone who took part today, you all deserve a huge cheer from us all!
