First time my gyms been open since March so I took the first available time slot (only 25 allowed at one time) We’ve had a really massive heatwave come through so I was very well hydrated in addition to what I was drinking during my workout. I felt the twinge in my bladder whilst I was on the treadmill but held it knowing I’d be going swimming later. Since I was the only one in there I thought what’s the harm and released a whole bladder full into the pool. After 20 minutes of swimming, I had to go again but this time I slowly released while I did laps in the pool.
