Here are some tips from a seasoned runner,
1) Warm ups are very important..
2) drink a litre 30 mins before you start.
3)when you start, jog slow at a pace, coordinate yr breathing with ya steps.
4) when u breathe in, make sure you can hear your breathing.
5) get a waistband to wipe perspire if u perspire buckets.
6) get a small towel, wet it but not like a wet towel, justly moist.
7) sling the towel across ya shoulders for the first 1 to 2km, then when u get tired, put the towel over ya head and run. (n.b., towel must be off light materials). (the towel acts as an layer to allow faster evaporation of excessive heat and moisture.

run fast at some intervals, as in 100 steps, 10 steps fast etc...
9) do not look far or on the ground, both are pschologically inducing, instead have your mind do some thinking, ex: happy times with gf, what u did which made you happy (remember: happy stuffs). If not, try counting, 1 to 100, then adding a noun in on the next 100 (ex: 1 car, 2 cars), follow by the melting pot (items u favour, ex: 1 lexus, 2 tits, 3 ladies etc...). ya mind will be shut out of fatigue soon enough.
10) if possible, have company, running causes anxieties which with say, frens, introduces emotional sharing (i.e., same plight, he can, i also can)
11) distance yrself however, at least 5m away from ppl u are jogging with
12) when you're tired, slow down, look up into the skies, this induces parallel rigid spinal homeostastis, bringing a balance to you body, brain induces dopahmines which will help regain vitality.
13) when nearing, u might wanna dash, my suggestion is to take 20 and 10.
paced 20 steps, fast 10 steps , then paced 10, fast 20 so forth, repeating
These are just a few examples how to manage ya 2.4km.
I have been running 5km 5 times a week, even after work.
