Real experience

How to train while busy.

From a civil engineering student who had no 2-hour windows.

2×

Fragmented time.

Split your long runs. 7.5km in the morning before class. 7.5km at night. Total 15km on weekdays without disrupting coursework.

19

No 20km long runs.

I never ran more than 19km in training. Race day wasn't a shock. HIIT + accumulated volume was enough.

60%

Stay in Zone 2.

60-70% of weekly volume in Zone 2. 30-40% in Zone 4-5. If you're always at Zone 3, you'll plateau at sub 1:55 and never break 1:50.
