The Dave Lloyd Mega Challenge will be held on 21 June in Ruthin, North Wales. It's the second year for this extremely testing ride, which is rightly billed as the toughest cyclosportive in the UK.
There are three options: 70 (Mini), 100 (Midi) and 150 miles (Mega) - ranging from around 2200 metres to over 5000 metres of climbing. This year, the long route goes over the hard side of the Bwlch-y-Groes (and it is hard) and all three routes finish just outside Ruthin at the top of the Bwlch Penbarass, which features a 30% hairpin.
It's not just the vertical gain that makes the Dave Lloyd routes so tough, it's the steepness of the climbs, the unforgiving road surfaces and - given that it is North Wales - the better-than-even chance of bad weather. The pay-off is that you'll see some of the most beautiful scenery that Wales has to offer and you will have a day on the bike that you'll remember for a long time.
