Well I've got no choice. I'll have to do it again.

Posted a few weeks back that I'd got to level 10 and was looking forward to riding the Alpe du Zwift. It was going to be the 4th version of Alpe d'HUez I'd ridden. I've done real life, Bkool, some simulator in my local bike shop that I can't remember and now Zwift! Except............ I then found out it was level 12 I needed to be at!! :cursing:

Reached level 12 last week, so decided to take it on and picked the route with the longer run in to get nicely warmed up.

I was feeling a bit tired and sluggish from lots of hard rides over the previous week or so and decided to take it steady and not push too hard. I'd just started the climb when my Dad decided this was an excellent time to call my mobile. He's been in hospital so I had to take the call. No problem with that, but that put about a 4 minute dent in to my time on the climb, so I'm going to have to ride it again now!

When I posted that I was going to ride it when I got to level 10, a couple of people were interested in how I felt it compared to the real Alpe d'Huez. At the bottom it felt quite realistic as IRL it's quickly up to an 11% ramp and pretty much stays at 10/11% for the first 4 hairpins. I think the real Alpe eases a bit after that, but its never easy and is a tough climb, especially after a tough start. Alpe du Zwift seems to have far more and greater changes in gradient than real life. I can't honestly recall hitting 14% grades further up the climb, more of a relentless climb generally around 8% plus. So once I was past the first 4 hairpins, I really lost any thought of comparing it to the real life climb and just accepted it as a challenge.

As a few others have ridden Alpe d'Huez since, I'd be interested in their thoughts on how the two rides compare.

I'll certainly do it again anyway, as I think it will be excellent training for a trip to the Alps, Pyrenees, etc. And next time, I'm not answering the phone, Dad! :stop::laugh:

Others more experienced in riding both (Simon Warren) say that Zwift has nicely mirrored the differing gradients. All i can say having ridden Huez IRL recently is that it seemed much the same. Frigging tough start, easing off and i would say lots of changes in gradient there but some ramps here and there especially after the 3rd or 2nd last bend. 59min in zwift but 1h 14m 38s IRL with a loaded up bike etc. I would like to think i could knock it down to 1hr 10 with better pacing perhaps even less but that may be wishful thinking.
 
just getting to the top is my target :cheers:

I think I was about 1h 18 IRL compared to 1h 15 on Alpe du Zwift.

IRL I rode quite conservatively early on as I didn't want to blow further up the climb. I remember being slightly disappointed and thinking I could have ridden it faster, but then If I had maybe I would have struggled further up anyway. Who knows?

The time tend to suggest that Zwift have done a good job in producing a pretty good replica of the real Alpe. However, I still say that I can't remember any 13/14% ramps on the real climb.

Both are still good climbs.

I remember doing it in BKool, and I though there were a couple of 13/14% sections after Dutch corner ... Not particularly long but they were there. ... I've also done it in BRVR and again there were some sections at 14% after dutch corner ... I do wonder if they were the inside of the hairpins as taken by the car, which is a different line that we would take on our bikes (Ride the outside of the hairpin reduces the gradient ... Allegedly :rofl: )

I thought you were faster than me on the Strava segment for the Alpe, so is 75 to 80 minutes your overall time including the run-in?
Checking on Strava, my fastest time is 66 mins. I have a feeling though that I did this on the Pro and not the Kickr (the ave watts for the ride look too high). My other rides are 71 mins, 75 mins, 76 mins, 78 mins, 81 mins, 84 mins. I need to hide the fast time and remove from the Strava times.

These are climb times for the Alpe. Add a 10 min run in, plus a 10-15 descent if you want to get those extra free km's too :smile:

Add bike weight and bottles to your weight and ride it Alpe d Zwift. I'd reckon your times would be quite near the real life. To me it felt the same effort just slower in the real Huez. Not got round to doing that experiment

Yeah, we were riding heavier than anticipated, me with lights, camera, 2 water bottles-though pretty much emptied one at the start, food, puncture repair kits/tools etc. Lee and Tommy at 1 h 6min.
There were a few people riding up without water bottles etc. but they may have been local club riders.

We have to be careful to choose the right course comparison too. I suspect many of us were caught out as we rode onto the town and looked for the markers to take us past the podium finish and around the roundabout to the Chrono finish. Thats not a mistake made twice.
This is the the official chrono course time for us CC'ers.
