14week Marathon Training Plan: Week 10, Session 2: Yasso 800m

Twenty-ninth Session: Week 10 Session 2: Yasso 800m x 10
Goal: First Marathon (Sundown Singapore 25 March 2017)

I decided to cycle out to the Kallang track as a warm up for this speed session. My legs were on the mend after the failed Sunday session, so was looking forward to a good session. Five minutes into my ride, it started to rain very heavily. The 45min ride was a stop, find shelter, resume and repeat journey as the rain was short and heavy in parts. My training partner had sent me a picture (see below) of the track during my ride, and I should have brought along my flippers instead. After a frustratingly and careful ride, I arrived at the track, and to my surprise the track had drained the water really well. Amost all dry with only a few puddles remaining. The rain won't stop us from training!

Main Set: 800m in 3:00mins with active recovery for 400m in 3:00mins  x 10
The last track session I completed was the Yasso 800m with 7 repeats, almost a month ago (Jan 24th). We jogged two laps around the track as warm up and set off after a quick drink. We used the same game plan to alleviate boredom by rotating lead pacers on each 800m repeat. The training plan calls for 3:00mins active recovery, but we were managing around 2:35mins for first 3 sets, and 2:45mins for the remaining sets. We viewed this as a positive change as we were able to have our legs and body recover faster before each 800m. Each 800m was spot on or close to 3:00mins duration, with the largest difference coming from the first set, recording 2:56mins in duration.

During the 10 x 800m set:

Average Heart Rate: 151 bpm (includes recovery)

Max Heart Rate: 174 bpm
Recovery Heart Rate (1min after finishing 800m): 1: 125bpm, 2: 134bpm, 3: 126bpm,  4: 139bpm, 5: 143bpm, 6: 144bpm, 7: 143bpm, 8: 150bpm, 9: 138bpm, 10: 143bpm
Cadence: 182

Session Analysis / Review:
(24/42 sessions completed): 57%,  (1/42 sessions failed): 2%, (4/42 sessions missed): 10%, 
Total Plan (29/42): 69%

Session was comfortable. Legs were starting to tighten up (hamstrings mainly, and I'm guessing due to the increase in stride length to accommodate the increase in speed), but nothing serious. Breathing felt a little harder than what I remembered from the last track session, and the HR data also supports that with values higher. I attribute this to the lack of track (speed) fitness, and I should start to see an improvement as I regain consistency back in the plan. The ride home also helped to warm down the legs, by flushing out the lactic acid. No limping or tightness whilst enjoying my dinner at home.
