6.6 miles fartlek

Led a depleted fast pack in a fartlek round half of the old club 5-mile championship route and up past the ski club. There were 8 fast bursts of which 3 were uphill, 2 were downhill and 3 were on the flat. Felt quite fast in places in the adiZero Tempo once I had warmed up. Distance was 6.57 miles, max HR for the session was 186.

HR zones: 2.5%, 42.3%, 37.5%, 16.3%, 1.5%
