Last year I rode the 140 cyclo and it had been raining in the days before the Ronde. The cobbles were damn slippy and when the MTB route shared the road with the cyclo participants you could see they were plastered in mud.
This year was bone dry hence able to get round the 100km well under 5 hours.
This year was the first time for the 100km MTB and the route was ok. To be honest it is not so special on the MTB part of the event. We’re just there to make some more profit for the organisers but there are no other MTB events on the Saturday.
If you enjoy your Belgian riding but fancy something on the MTB one of the very best events (without having to travel too far) to ride is the http://www.herdermarathon.be on May 23rd. This takes in many of the same hills as the RvV but uses off-road paths instead of the tarmac. Choice of distances up to 140km with >2700Hm climbing. It costs an amazing €6 to enter with 5 well supplied food stations along the route.
Did you know the RvV sportive will be also available on the Friday next year? There were 19.5k participants on the Sat this year plus up to another 4k on the Friday!
