So to do a sub 11 on the Up Comrades one needs to finish at just below 7:35 pace. A simple 41 s /km slower will be a sub 12.. Ah the simple basis of pacing. I do round these off a bit, but it is your average pace that is critical. Garmin has a Race Screen if you have ConnectIQ, this will allow you to correct the distance when doing an accurate race eg Cape Town Marathon where I corrected my watch distance about 4 times, actually seeing how the 1m is added in for every km as per measuring guidelines- this prevents a race being short (page 15... MeasurementOfRoadRaceCourses.pdf ) plus the extra few m for not taking the shortest line. This race screen kept me on target for a 4:34:30 finish time for a G seeding , some running was involved and mat to mat. I used the Race Screen on Comrades and I believe it helped me as by changing that data screen I could see exact finish time at that ave pace.. No fade is built in but that is easy to workout. I tend to round off my race distance to allow a bit of fade even in the final stretch.
Looking at my above walk, the first km was 27 too slow, no really an issue (yet) then I lost another 35 secs but this is my hardest hill on my route.. now I am 62 seconds behind target, with 13km to go I need to now average 7:15 ie 13 x 5 secs is 65 seconds to get below my 7:20, where a runner has the advantage is in being able to run downhills below 6min/km and gain that 62sec plus in 1km . I need to chip away at the deficit slowly. Remember every km I do faster than 7:20/km will eat into the 62sec and every km slower will add to it . 3km add another 13 secs, but then i gradually wore away at the deficit till in the 10km I erased it. I then managed to build up a cushion and get ahead of the clock.
I hope this is not too confusing, if it is send your queries...
