Running (Time Trial) 14:56  3.0 km (4:59 / km)

Had a solid first 1,5k was sticking to my under 4min/km planned pace.
After that, well it went down hill. Major chest pains and really struggles with breathing, thought it was best to slow pace down incase - heading to the Doc to see that it is nothing major as this wasnt the first this had happened
Running (Cool down) 10:00  0.4 km (25:00 / km)

With needing to get my heart rate down, so i could actually breathe. Took a really easy walk around the track and sat down and did stretching.
