5th from the back would be an improvement over my last performance so would be happy with that
Four times. We go up it four times
As
@Joffey says, blast out the starting gate .... the first 2 minutes of a Zwift race can dictate your whole ride. Get dropped from the off and there is no getting back.
So blast out and try to find a pack that is at your level. You will go much, much faster in a group blob in Zwift.
As for the climbs .... ignore everyone else around you and go at your own pace UNTIL you get near the top and then look for wheels to ride with ... could be someone a few seconds behind you (so rest a bit and let them catch you) or a few seconds ahead (so dig a bit harder to ctach them and get a free ride down the other side and on the flatter sections.
Oh .. and try to enjoy it
