Let's execute the file writes.

I'll help you add an endpoint to retrieve a single race. I'll update the `RaceController` to include a `show` method and then add the corresponding route in `routes/api.php`.

First, let's update the `RaceController.php`:

<write_file>
<path>truncated.../Controllers/RaceController.php</path>
<content><?php

namespace App\Http\Controllers;

use App\Models\Race;
use Illuminate\Http\JsonResponse;

class RaceController extends Controller
{
    /**
     * Display a specific race.
     *
     * @param  string  $id
     * @return \Illuminate\Http\JsonResponse
     */
    public function show(string $id): JsonResponse
    {
        $race = Race::findOrFail($id);

        return response()->json($race);
    }
}
</content>
</write_file>
