Completed c25k and started out on bridge. Got to the point where I could run 8k or so and all well.
All just fine and dandy until one day saw me have to suddenly dash and hide in a gateway at the side of the road as the best cover I could find and poo. I put it down to maybe something I had eaten.
But, to cut a long story short this problem is now a constant for me. It has continued for about 3 weeks now and if anything has worsened to the point where reliably, as soon as I reach 2 miles, even at a slow and easy pace, then before I get to 3 I am going to have to go...and then go again...and again.
As soon as I stop, the problem stops. Literally. From being in a desperate state I can be just fine within about 15 seconds as long as I walk and don't run. It never happens at any other time than when I am running.
I initially thought maybe this was just one of those things where you have to back off a bit and it will get better on its own with a rest. Maybe my insides could get an over-use injury like my legs. But that doesn't seem to be happening. Its not going away. Its looking like the end of my running - well, any distance beyond 3 miles anyway. I'm not really concerned that its anything serious health wise - it is purely running related and the problem does not exist at any other time. The contrast with how I am the rest of the time, and how quickly I go back to that if I stop running, is startling - I'm absolutely fine, regular and normal 100% the rest of the time. But obvs its a showstopper when it comes to running a 10k.
I've read as much as I can about it and I've tried no hot drinks, caffeine etc before I go (I run first thing in the am so I haven't eaten since the day before), not eating spicy food or beans or major fibre etc evening before - nothing works. I can find plenty that describes the problem online but nothing really that anyone has managed to do about it that is a definitive solution.
I just want to ask - has anyone else had this and found a solution? Is Immodium the answer? Did it ever just go away of its own accord for anyone? I don't really want to bother my GP with this in the current covid circumstances as they already have their hands full and the problem is self inflicted. And one pretty conclusive solution is in my own hands right now - stop the running. But I'm hugely disappointed to have to do that after all my hard won progress.
Any advice gratefully received.
