Here at the running blog we would like to wish all you London marathoners a very good day on Sunday. May the weather be perfect (it's looking good) and the PBs be bountiful. Remember to come and share your experiences on Monday on our regular Monday morning debrief thread.
There are also two other places you can share your moments. Firstly, our own competition via our new GuardianWitness platform – tell us why you are running, and you could win £100 for the charity you are supporting.
The Virgin London Marathon is also holding its own competition on Twitter. Share your favourite moments from race week at @londonmarathon using the hashtag #VLMbestbits. There are 10 goodie bags worth over £100 each for the lucky winners. Find more details on the Facebook page.
