First time doing a late night run

Wanted to run today at 5pm but it was raining. At about 7pm, wife and kid went for a brisk walk and I did not join them as I plan to do a longer distance run.

Went to run around Neram Crescent playground garden in Seletar Hills Estate at about 10:05pm.
Forgot to start the watch timer for the first "lap"... each lap around my running route there is about 2.5km. Started timer only after the first lap. Clocked in 29 minutes for the final 5km run (the final 2 laps). So total distance covered is 7.5km and time approximately less than 45 minutes.

It was quite a leisure run and felt I can go another 2.5km easily but decided to stop as it is getting close to 11pm. My heart rate was mostly in Zone-3... a comfortable level .

During cool down, the heart rate reduced from 155bpm to 120bpm within 2:50 minutes. Not too bad. Goal is to reduce heart rate to 120bpm within 2 minutes or less... a faster recovery rate.

Overall quite an easy run tonight. Took a shower before going to bed. Slept very well after the run.
