You can add some condition to highlight a specific series:

        series: data.map(function (set, i) {
            if (i === 10) {
                return {
                    name: 'Runner ' + i,
                    data: set,
                    shadow: false,
                    color: 'red',
                    zIndex: 1
                };
            }
            return {
                name: 'Runner ' + i,
                data: set,
                shadow: false
            };
        })
