Cori Bullett

London Marathon 2025

I’m running the London Marathon 2025 to fight for lung health!

Hi everyone!

My name is Cori and I am running the London Marathon (eep!) to raise money for Asthma + Lung UK.

Every minute, someone in the UK is diagnosed with a lung condition. 

I was diagnosed with exercise induced asthma as a child, but it didn’t affect me often and so I let my inhalers run out and didn’t replace them. 

Then about 6 years ago, after a netball game, I had an asthma attack, which luckily wasn’t as serious as it could have been. Since then I have taken my condition much more seriously, and so I am running the marathon to prove that asthma doesn’t hold me back, whilst raising money for an incredible charity!

Asthma + Lung UK is the only UK charity that fights for everyone’s right to breathe. Every pound I'm able to raise will take us a step closer to a world where everyone has healthy lungs. Just £22 allows one of Asthma + Lung UK's nurses to answer a call on the Helpline, offering potentially lifesaving advice. 

Any donations are very much appreciated, but as a little added incentive…

£10 donation: guess my finish time and the closest guess wins a sweet treat baked by me! (Brownie, cake, fudge etc - tbd with the winner!)

£25 donation: the above PLUS you can add a song to my marathon playlist

£100 donation: all the above PLUS you can pick a mile and I will record you a thank you video as I pass that mile

The weeks roll by…

Monday 2nd Sep
Last week I ran 12.5k!!!

I drove to Sonning and took the lovely scenic route along the Thames river to Reading, hit the turnaround point and ran back. 

I am so proud of myself, because I only walked 4 minutes in the entire run, which lasted around 1hr 34 minutes. 

I’m going to do another 12.5k again this week to try and build the consistency. 

I think if I can get to a “comfortable” half marathon before Christmas, I’ll be in a really good place starting official marathon training next year!!

Longest run yet…

Thursday 8th Aug
I ran 10k today!

I consciously tried to slow my pace, so that I could go further but what I didn’t factor in were the hills!
I didn’t think I lived in a particularly hilly area, but I now definitely disagree…

I comfortably ran the first 5k but then had to walk for a few minutes. I did start running again, and managed to run most of the rest of the run. 

It’s not the best 10k I’ve ever done (out of those like 3 times) but I did it! It took me 1hr 16 minutes and by 10am I was done with my exercise for the day!

And as I said to myself at the end, my 1hr 16m 10k is the same distance as the Olympians 29 minutes 10k!

A little bit of my running history…

Wednesday 24th Jul
I would consider myself ‘somewhat fit’. 
I always played team sports like hockey and netball as a kid, and still play netball now. I play Wing Attack or Centre, both of which involve a lot of running!
I also go to the gym on a pretty regular basis, and enjoy doing HIIT classes. 

But this is running. This is a whole different type of fitness 😅

Like everyone else, I got into running during lockdown when we were allowed our one exercise outside for the day. I started running pretty regularly with an aim to run a half marathon before I was 30.
I was running regularly and was so proud when I got to 15k without stopping! (Whilst listening to the Harry Potter audiobook, thank you Steven Fry!). I said to myself, ‘next time I run, I’ll push for that half marathon, 21k’. And then I never ran again…

Until earlier this year when I made a joke to my parents that I’d see them at Bracknell parkrun on Saturday, and then decided to follow through with the joke and send them a picture of me at the parkrun asking them where they were. 
It was funny at the time but now I realise it was the start of the rolling ball which means I’m now running a marathon…

Anyway, I’ve been a fairly regular park runner since I picked it back up at the end of April this year. My current PB is 31.20, am I’m looking to reach that 30min milestone sometime soon!

I’m writing this as I have just got home from my first ‘official’ marathon training run. 6.6K round the streets of Bracknell in 44minutes. Only another 35.6K to go!
