It's a rather big day at the gym today - after spending five tiers of the plan alternating walking and running for gradually longer stretches of time to build up my endurance, the target for today's session is:

Brisk five-minute warmup walk, then jog two miles (or 20 minutes) with no walking.

This is a bit of a daunting task - there have been noticeable leaps before, but this one beats them all. Previously, the greatest amount of non-stop running time required by the plan was eight minutes, though when testing myself I managed one entire mile (just over 11 minutes) without stopping. This suddenly introduces a marathon session (if we discount the fact that a marathon is thirteen times this for a moment) that at my pace should last about 23 minutes - nearly three times what I know I can do comfortably.

Still, I have this to fuel me - it is apparent that the cafe on the corner next to us interprets "Crab sandwich" as "Open a tin of crabmeat and make your best effort to jam its entire contents between two groaning slices of bread".



Tonight is going to feel either really amazing or really sore.
