Friday Fartlek: 3x 12 minutes

This session will develop your speed over 10km but also for 5km and half marathon events.

Each week I will be posting the Friday Fartlek Run Sessions that you can do to enhance your running. Fartlek is a Swedish term that runners often use and it means speed-play. See a previous post about training intensity (levels) to know how hard to work.

This session is similar to this workout from November, but instead of being based on distance, it is based on time. This session can be done instead of the seventh week in the 8 weeks to a faster 10km programme.

Depending on your ability the intensity of the intervals will vary:

• Group E – currently running between 55 & 60min for 10km
• Group D – currently running between 50 & 55min for 10km
• Group C – currently running between 45 & 50min for 10km
• Group B – currently running between 40 & 45min for 10km
• Group A – currently running between 35 & 40min for 10km

3x 12min

• 10min Warm Up Level II;
• 3x 12min Level IV, 5min Level II RI;
• 10min Cool Down Level I-II;
• 10min Stretching

The warm-up should be done at an intensity that is steady but not overconsuming at Level II. Run for a minimum of 10 minutes.

The main set: run hard for twelve minutes at Level IV at the pace in the chart below. Run at Level II for five minutes as your Rest Interval (RI). Then repeat a total of three times.

If, for example, you currently run a 10km event at 53:45 that puts you in Group D.  Therefore your main set involves running for three reps of 12 minutes at 4:45 per kilometre and having a five-minute Rest Interval (RI) running at a pace of 6:30 per kilometre.

Group	12min pace (min/km)	RI pace (min/km)
E	5:15	7:20
D	4:45	6:30
C	4:15	6:00
B	3:45	5:30
A	3:20	4:50

The cooldown is at a low intensity, jogging for a minimum of 10 minutes.

Finish with 10 minutes of stretching to assist with the recovery.
