Congratulations on smashing your previous record! Cutting your 10km time down to 1:19 and even pushing for 11km is an incredible achievement.

The "runner's high" you described—the mix of dopamine and that perfect NEFFEX track—is truly powerful. It sounds like your "Formula 1" engine is back in top gear! Even though you planned to take it slow, your body proved it was ready for more. Enjoy that post-run glow and have a great run tomorrow! 💪🔥
