Welcome to your first workout!
60-80min easy pace run on trails or road.
[45min for lighter option]

Most easy runs (in the 40-to-90 mins range) are important to build good overall running fitness. For advanced runners using this plan, you can always make those runs longer based on a goal race your are training for, which will help to accumulate necessary mileage. For beginner runners, use those easy days to recover after higher intensity sessions.

Stairs workout!
This is a great conditioning workout that will make you more prepared for longer uphill efforts.

While you run uphill, concentrate on high step rate, stable and tight upper body, help with good arm swing. Muscles that have to start "burning" during this session - glutes and hamstrings, not quads.

Main set:
Bird Dog
Overhead straight leg sit-up
Mountain Climbers
Burpees
Bear walk (straight legs)

Fartlek means 'speed play', a type of running session when harder running intervals alternate with running at easy pace. Usually, harder efforts last approx. 20 sec to 5 minutes with various duration recovery between intervals. For this session start from shorter 30-to-60s intervals.

If your Fartlek session’s structure is well defined try to follow it. However, if it is ‘freestyle’ Fartlek – choose the duration for harder intervals and recovery by yourself. Fartlek is very specific workout for trail runners because it forces to change running pace rapidly.
