I have built a custom map that builds directions from a single point to a clicked marker, however I am having trouble figuring out how to display the total distance and travel d

You need to calculate the total distance and time from the data in the directions response. Related question: Distance from point A to B using Google Maps, PHP and MySQL (my answer, not the accepted answer, does that).

calculate the total distance and time:

function computeTotals(result, infowindow) {
  var totalDist = 0;
  var totalTime = 0;
  var myroute = result.routes[0];
  for (i = 0; i < myroute.legs.length; i++) {
    totalDist += myroute.legs[i].distance.value;
    totalTime += myroute.legs[i].duration.value;
  }
  totalDist = totalDist / 1000.
  infowindow.setContent(infowindow.getContent()+"
total distance=" + totalDist.toFixed(2) + " km (" + (totalDist * 0.621371).toFixed(2) + " miles)
total time=" + (totalTime/60).toFixed(2) + " minutes");
}

call it and put the total distance and time in the infowindow:

function calculateAndDisplayRoute(directionsService, directionsDisplay, distinationOrigin, destinationMarker, infowindow) {
  directionsService.route({
    origin: distinationOrigin,
    destination: destinationMarker,
    travelMode: google.maps.TravelMode.DRIVING
  }, function(response, status) {
    if (status === google.maps.DirectionsStatus.OK) {
      directionsDisplay.setDirections(response);
      computeTotals(response, infowindow);
    } else {
      window.alert('Directions request failed due to ' + status);
    }
  });
}

proof of concept fiddle

code snippet:

function calculateAndDisplayRoute(directionsService, directionsDisplay, distinationOrigin, destinationMarker, infowindow) {
  directionsService.route({
    origin: distinationOrigin,
    destination: destinationMarker,
    travelMode: google.maps.TravelMode.DRIVING
  }, function(response, status) {
    if (status === google.maps.DirectionsStatus.OK) {
      directionsDisplay.setDirections(response);
      computeTotals(response, infowindow);
    } else {
      window.alert('Directions request failed due to ' + status);
    }
  });
}

function computeTotals(result, infowindow) {
  var totalDist = 0;
  var totalTime = 0;
  var myroute = result.routes[0];
  for (i = 0; i < myroute.legs.length; i++) {
    totalDist += myroute.legs[i].distance.value;
    totalTime += myroute.legs[i].duration.value;
  }
  totalDist = totalDist / 1000.
  infowindow.setContent(infowindow.getContent() + "
total distance=" + totalDist.toFixed(2) + " km (" + (totalDist * 0.621371).toFixed(2) + " miles)
total time=" + (totalTime / 60).toFixed(2) + " minutes");
}

function initMap() {
  var directionsService = new google.maps.DirectionsService;
  var directionsDisplay;

  directionsDisplay = new google.maps.DirectionsRenderer({
    polylineOptions: {
      strokeColor: "red"
    }
  });

  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 13,
    center: new google.maps.LatLng(25.03086141, -77.39945412),
    mapTypeId: google.maps.MapTypeId.ROADMAP
  });

  directionsDisplay.setMap(map);


  var marker, i;

  var infowindow = new google.maps.InfoWindow();

  for (i = 0; i < locations.length; i++) {
    marker = new google.maps.Marker({
      position: new google.maps.LatLng(locations[i][1], locations[i][2]),
      map: map,
      icon: locations[i][3]
    });

    google.maps.event.addListener(marker, 'click', (function(marker, i) {
      return function() {
        var distinationOrigin = new google.maps.LatLng(25.084536, -77.330704);
        var destinationMarker = locations[i][1] + ',' + '' + locations[i][2];
        infowindow.setContent(locations[i][0]);
        infowindow.open(map, marker);
        calculateAndDisplayRoute(directionsService, directionsDisplay, distinationOrigin, destinationMarker, infowindow);
      }
    })(marker, i));
  }
}

google.maps.event.addDomListener(window, "load", initMap);
