I was so sceptical. I thought all it would do is make me need the toilet half way through a run.
The first time I used it I did my longest run of the year so far and loved every minute of it. No rethinking my life choices after just 2mins. No “I can’t do this” thoughts. And even after an hour I felt strong and that I could have run much further.
A fluke I thought, must have just been a good run day. So my next run was on the treadmill which I don’t enjoy. But again I felt strong throughout my run, felt like there was an extra spring in my step and again still felt good at the end.
So I’m a convert now!
For info I’m just getting back into running after a few years away. Running 10-12k distance currently but with this magic stuff I might even consider going back to running half’s!

Pre Run is the little kick up the backside I need to stop making excuses, lace up my Prime X3s and get out the door.
It gives me a proper boost without making me feel like I can hear colours. Ten minutes later, I’m ripping up the tarmac and pretending I’m much faster than I actually am.
Tastes good, works well and gets the job done. Definitely part of my running routine now.

Firstly this has been superb changing how the start of my runs feel. Tried a few times before I’ve left review and it’s really made my legs feel very different. Only criticism is I’m not mad keen on the flavour but if it helps like this I’d still drink it !
