Bivouac has opened at the head of markets for the Black Caviar Lightning Stakes

Gun straight track horse Bivouac is the favourite with Sportsbet.com.au to take out the Black Caviar Lightning (1000m) this Saturday at Flemington.

The James Cummings trained four year old was stunning the last time he raced, which was down the straight in the VRC Sprint Classic during the Spring. Resumes on the weekend and heads the market at $2.80.

Nature Strip, a beaten odds on favourite in this race 12 months ago, is on the second line of betting at $4.20 ahead of stablemate and star filly September Run, who is a $5.50 chance.
