3 x mile in Arena

It is almost two years from the last time I was running in Esport Arena and track repeats in the first place. Went there tonight out of the blue while the kids played tennis. I was painfully slow. Clocked in 5.32, 5.34 and 5.38 with 1 minute breaks. Avg 3.29/km. Was hoping for at least four repeats taking into account the great trail run less than two weeks ago. But tonight I just ran out of legs, lower back (in curves) and time. Perhaps reached an overall personal low.
