You have 2 mins to push home from when the race finishes as long as you don’t have any outside help which is what he done Thomson just pulled his bike out from under the fence started it again rode it home for the point seen it loads of times ,riders leaning there bikes over to warm tyres must be pretty common as every rider does it at the start but monarchs riders were saying they could see smoke coming from the back tyre but being barkers lawn mowers like people were saying lol maybe it was engine oil burning out exhaust or the primary chain getting too much oil and burning off like you see after most races
