I read that you should always have 'a try' before going out running as the only thing that will stop you mid-run is needing the toilet. Not convinced.
So far, I've been stopped by:
Fly in the eye
Fly in the mouth - yum
Dog needing a wee/poo (why didn't the dog try before we started running?)
Jogging bottoms falling down
T-shirt riding up! (oh the joys of being pear shaped)
Mobile phone making a leap for freedom and dangling on the end of the headphone chord
Anyone add any more?
ha ha, I always have to pull my top down too, but I coordinate that with the walking segments.
I did have to stop when my app crashed, that was a pain.
My mobile phone has tried to make a leap for freedom in the past, too - it's terrifying isn't it?! 
I've also been stopped by:
A branch catching on the jacket tied around my waist - twanging me backwards
Just HAVING to stop to say hello lovely old man and Cairn Terrier (I had a Cairn Terrier as a child)
Having to shift bits of strewn roadworks barrier out of the way
Traffic
Shin splints
Sudden onset of womanly pains
Burger van complete with inconsiderate chatting customer and dog, having a sleep, on the entire pavement
Inconsiderate cyclists on the pavement in the dark with no lights on
Flip belt riding up (more pear shaped woes)
Getting lost in a field when the path vanished before my eyes
It's a tricky old thing, this running lark!
.... key heading down inside of capri pants out of pocket(not a zippy one!)
.... getting lost!
Trousers falling down yes!! So glad I'm not the only one!!
Having to cross the road when traffic is heavy!
Small child insisting on coming who then moaned week one! Promptly told to say in middle of playing field whilst I ran round her!
Hills!!
Tripping over a tree root and going A over T
heheh! Usually it's the dog lead I'm tripping over..
Inadvertently fastening sports bra too tight and nearly asphyxiating 
I ran this morning in a new shock absorber bra and a compression top. I swear my rib cage has narrowed by 2 inches. .........
I find my sports bras not really much more uncomfortable than sore boob bounce. Ouch!
I insist that provided you maintain a running motion, you're good - so in the case of canine comfort breaks, running on the spot will do. In fact learning to 'pick up' whilst moving has probably improved my coordination!
Excellent idea - I shall practise that!
Being mounted by a large black labrador 
lol
OMG LOL......... 😂😂😂
OMG. I have a new nightmare!
T shirt riding up - Not just Pear shaped girls - us hourglass girls have the same problem 
a head wind so strong I was running and standing still like on a cartoon
Snot - I am a really snotty runner
My mobile has also made a mad bid for freedom. Funny how they choose your run to do this
Getting lost
My dog lying down and refusing to go one step further !!!
Mine do too - though what I like is that I am now FITTER THAN MY DOG! hahahahhaha
never thought of it that way haha
Oh yes I'd forgotten about the snot, although I've now become quite adept at fishing out the tissue & blowing without breaking my stride!
Ha ha , this is a brilliant thread, very funny ! xxx
Needing to wipe the sweat out of my eyes with my shirt!
Finding my capris at half mast.
Giving some idiots in a caravan directions
Being jumped at by a very large, but fortunately friendly dog!
Fantastic old steam train and posh carriages at a level crossing.
Huge puddles and trying to figure out how to get across
Hills
Going on a different route and leaving the car at home and worryingly trying to figure out why the car wasnt in its normal space at the park
Reversing cars need adding to the list.......more than once......hello the pavement is for pedestrians.....I shouldn't have to break stride to give way....or so you'd think 
Cars parked on pavements are the bane of my life. I'm for ever clouting wing mirrors with my hip as I squeeze past. Roads are for cars, pavements are for pedestrians.
Yes I can blow my nose whilst running no problem whatsoever! Traffic - I jog on the spot at the side of the road until the cars have cleared - feel a bit foolish but never mind and often people are nice and wave me across in front of them
I had to stop during one of my week 6 runs and tie my shoelace, even though I always do a nice tight double bow. I'm ashamed to say I'd run for at least 2 minutes with it dangling free, dangerously, because I really didn't want to stop! I added time on at the end of the run after Laura said walk, to make up for it.
Oh yes , I forgot about my shoelaces ! Flippin bane of my life they are , tie 'em too tight and they make my feet numb, too loose and they come undone...
Pah ! xxx
Ankle-length socks slipping off :-\ lol
A pack of dogs running about like lunatics in the park and one of the bigger ones motioning to 'rugby tackle' me.
A woman and child blocking a stile by jamming a mountain bike in it.
I once dropped my phone on the treadmill. It landed on my foot then shot off the back of the treadmill. I ignored it and some kind soul handed it to me WHILE I WAS STILL RUNNING!
Shoe laces came undone. I stopped to retie them, then went for a pee, and someone handed in my belongings to the receptionist and stole my treadmill.
1) a runaway beer keg rolling down the hill towards me. The drayman let it get away whilst dropping it off the back of the lorry (technically, I didn't stop, but rather did a Usain Bolt impression as I sprinted out of it's path)
2) halfway round my first parkrun - stopping to read a text message from home. The message: "Get a move on!"
A runaway beer barrel would definitely improve my time I think. Waaaaaaaaa!
Erm... sorry to lower the tone here, but I can add needing a 'wild wee' on my longer runs! Fortunately they are out in the middle of nowhere and I have a Shewee so it's fairly discreet - until Mr. Strava shouts 'Run paused'
Or not as the case may be. Lol lol 😆
- ice on path
- level crossing barrier (when I lived in the 'burbs)
- cattle gate latches ( when I moved to " the country")
- end of the esplanade (on holiday)
- taking photos for this forum!
The main cause of me stopping is heavy traffic when I am crossing the road, though an articulated lorry coming down the road can give you a burst of speed as you cross in front of it!
Stopping! w8/R2 -(edit actual didn't stop walking just stopped running) 
Finally run up that hill non-stop 🏃♀️😃🏃♀️
Time to stop running it’s the end for me
Goodbye walks, hello non-stop running. Yikes!
