Identifiers and hence type properties/enum cases cannot start with numbers. You need to change the naming convention for your enum.

enum RaceType: String {
    case fiveK = "5K"
    case tenK = "10K"
    case marathon
}

It's not obvious that enum cases have anything to do with variables. Use *identifiers* to cover all those cases without implying a stronger relationship between them. – Caleb Nov 12 '18 at 12:42

As a cheat you could use emojis like ５ or as the starting letter.
