The inside radius of a running track is 36.4 meters. Each lane is about 1.2 meters. Length was taken from IAFF regulations which states an 85 meter straight, but ok, take 80m. Therefore the total length is:
80 meters + 2*radius (72.4) + 2* 8 lanes (2*8*1.2) = 162.5m
Still way too much to fit inside SMS.
