This morning I ran WK8, R2, and during the 28 minutes ran a total of 2.1 miles. I had a Garmin Forerunner 10 for my 50th birthday yesterday, and used it for the first time this morning. Only had it set on miles, so not certain what 2.1 miles is in kilometres. Up to now, l've never known how far I'm running so it came as quite a surprise that I only have another 4 runs to go, and another 2 minutes running time added on to the 28 I am currently doing, and getting nowhere near the 3 miles estimated. I know there are lots of comments on here about it being all about taking it slow, and it's better to finish the run, than exhausting yourself, but is 2.1 miles a good distance with only another 4 runs to go?
