Well I have been curious about the 21K I am running on Saturday and the times posted from last years race... they seem very fast for this course... So my OCD kicked in and I have ran and mileaged the entire course and through my Garmin estimates the course is atleast 1 mile short... which would make sense on why times seem fast on the course...it is a tough course with 80% or more of it uphill... anyway did the last 3.5 miles which to get it to the full length would have had to be closer to 5 miles, so it will be interesting to see what happens on Saturday... whether they add more or leave it, i think they will leave it and I hope my Mileage is right. Ran the trail then ran back on the paved road back to my truck! Did some fast miles on the way back down, and I am always amazed when I push hard on downhills how fast marathoners average 6 or better per mile... |
