Before the 2018 thread gets confused with questions on how to enter the 2019 event I figured it's already time for the new thread even before everyones legs have recovered from this year.
The 2018 incarnation of the thread can be found here:
How to enter London 2019, main methods used by people here in bold:
Elite entry - run superfast and be invited.
Championship - run sub 1:15 half or sub 2:45 full for men, or sub 1:30 half or sub 3:15 full for women. Must also be a paid up member of a UK Athletics affiliated running club. Not all UK running clubs are affiliated to the correct body.
Good For Age - run one of the times listed on this page appropriate for your age category and have a UK address. They don't care about nationality, just that you have a UK address and the time. You need to apply for this between 1 August 2018 and 16:00 on 10 August 2018 and must have run the qualifying time between 1 January 2017 and 10 August 2018. New for this year is that getting the time will not guarantee a place anymore and the places will be limited to 3000 male and 3000 female. They have not fully described how they will assign these places if over subscribed, but expect it to be along the lines that they remove the slowest qualifying times from each age group until they reach the limit of 3000 entries.
They actually recommend that people applying for GFA places for 2019 also enter the ballot as GFA is not guaranteed. This will barely increase you chances of getting a place but if you are only just inside your qualifying time is probably a good idea.
Ballot - enter the UK ballot. Again you'll need a UK address, but time doesn't matter. https://www.virginmoneylondonmaratho.../ballot-entry/
Ballot must be entered between Monday 30 April and 17:00 on Friday 4 May
International Ballot - enter the overseas ballot. Less places available but worth a punt, you should be able to get away with entering the UK and overseas ballot without being noticed once you have appropriate address details for both entries. Same entry dates, Monday 30 April and closes at 17:00 on Friday 4 May.
Charity - find a charity who has places, convince them you can raise the cash, they give you a place. Will probably be in the region of a couple of thousand pounds you'd need to raise.
It's great just being able to copy and paste the post from one year to the next.
