Passive (rest) and active (jog) recoveries both have a place in the training environment. See Moniz Pereira for examples of Fernando Mamede and Carlos Lopes back in the 1980's and why they recovered as they did (it may surprise some).
Another form of recovery is the "float" (see Canova), which is more active than a jog recovery - e.g. 4x5km in 15minutes (say MP for his elites) with a Km float (of 3.30) in between for a total of 23km in 1h10+ for Marathon preparation (in this example float is about 85% of pace). For km's this could be 6x1km (400m float) =8km, where the km's are at 10km pace, the floats at 75-85% of that pace. If pace is 4min/km, then float at 80% is 2min for 400m, so 34min for 8km. For 3min /km the float would be 1.30/400m., or 25.30 for 8km. This is similar to the Oregon Drill (40/30), where the pace is 4min/mile (30sec 200m), and the float is 5.20/mile (40sec 200m, so 75% ). This a stressful session, but much like the old Aussie (with a Lydiard influence) session of stride/sprint the straights and float the turns, adds a different dimension to training than just repeats with active jogs or passive rest.
I do a progressive session of 5km, where pace is 5km DP-GP as follows: (1) 6x 500m (300m float) plus 200m sprint = 5km; (2) 8x 400m (200m float) plus 200m sprint; (3) 12x 300m (100m float) plus 200m sprint. The specific pace increases from 3200m to 3400m to 3800m, or 64-76% of Race distance at pace. This can be adapted for any distance. Really just a copy of the old Aussie track fartlek that Clohessy used for Deek and others. (there's was 400/200, where Deek would get down to sub 65 for the 400m and sub 40 for the 200m).
