  1. Sorry to hear that, Will. Hope it wasn't too far to run home! (Sorry, couldn't resist that one...
  2. Ferrari's grade factor definitely wrong for steep climbs. 4W/kg can never get you more than 1467VAM (since you'd be gaining potential energy faster than you were expending energy) but the excel graph shows 1600VAM at 20% gradient... Turning to the Strava, 4000m in 4hr is a hell of an impressive half day climbing, but going to be tough to maintain slightly harder than that non-stop for slightly over double the duration... Good luck to him if he does go for it though!
  3. Theoretically, 2.73W/kg gets 1000VAM ... on a hoverboard in a vacuum. That's 2.73W per kg of all up weight (inc bike, clothes, bottle, etc). Then factor in rolling resistance and aerodynamic drag too. For around 12kph, I'd guess that's around 40W for an average sized rider. Obviously as you go faster, RR & drag will increase, but as long as you can pick something that you're riding at low teens kph, then it's not a huge difference. But if you're going for a record, then as steep as possible (with gears to match) seems the most sensible approach.
  4. Slight thread derail (or maybe re-rail back onto the OT... ) A couple of weeks back, I was cycling up the Newlands Forest climb ("Trev's Bastard" for those of you on Strava) to head over the top Kirstenbosch on a family ride. Riding one handed and pushing a tired 6 year old up the jeep track with the other (try it sometime, it's a good workout!). A black Specialized (Stumpy?) E-bike came flying down the descent (not crazy speed - but anyone coming downhill looks like they're flying when you're grinding up at 5kph...). I moved us across off the smoother part of the track to make way. My 6 year old's 20" wheels hit a bump, he wobbled, I wobbled, we fell off (at about 4kph - no harm done). I resigned myself to having to push the rest of the way up the climb as getting a 6 year old moving and also getting myself moving quickly enough to "catch" him and push before he grinds to a halt and falls off is a tall order up the steep gravelly bit of the jeep track. 15 seconds later, the E-bike rider comes back up the climb, introduces himself as "Toren" and kindly offers to push said 6 year old up to the top of the hill, as he says he "feels guilty for making us fall off". (It really wasn't his fault - I chose to change our line to give him the safer line downhill, and falling off was entirely my own lack of skill/carrying enough speed to push 6 year old over the bumpy rocks). We gratefully accept and my 6 year old gets the fastest ascent of the second half of Trev's Bastard in his life! Anyway, the point of this is to say (1) a belated "thank you" to Toren (if you're reading this) - you didn't have to turn round, but it was really kind that you did. (2) I don't much care if you're motor assisted - I'd rather have the mountain filled with people like Toren than people too busy chasing the next Strava segment to nod hello. (To be fair, very few people on the Newlands-Kirstenbosch track fall into that category). Regarding events, I don't think someone riding the Cycle Tour on an e-bike diminishes the achievement of someone who rides unassisted. It's obviously not fair to have e-bikes *race* against unassisted riders, but that's no reason to prevent them from taking part especially if it makes the sport accessible to more people. As an occasional tandem rider, I think there's a direct parallel with tandems - weaker riders can gain assistance from a much stronger riders. But no-one seems to complain about 12 year old kids doing the Cycle Tour on the back of a tandem with a parent... Should tandems be allowed to ride in $ and compete for the win? No, of course not. Should tandems have a dedicated start group for their own competition if they want? I don't see why not. Should tandems be welcomed as part of the cycling fraternity and allowed to participate in the massed start? Absolutely. Replace tandem with e-bike and I don't have a problem with that. As long as they're not trying to pass themselves off as unassisted riders in races, I don't see why anyone else should either...
  5. I must've set a record for quickest ever being dropped from your group... I didn't even make it onto the N2, as at the third group-concertina-emergency-brake-test in the first 500m, someone went into the back of me and my chain jammed. By the time I'd got off, removed the back wheel, reseated the chain and replaced the rear wheel, @ were well on their way up the N2, and I wasn't going to get back to them soloing into that block headwind, so soft-pedalled and waited for &, which was fine until I got caught behind the crash at Misty Cliffs. Almost regained the front group at Slangkop, but couldn't close the last 30 metres into the headwind on Kommetjie Road. At least I got to enjoy the last 30km instead of having to bite my stem to stay with the racing snakes over Chappies and Suikerbossie! Condolences to the family of the rider who died.got Some nasty crashes out there too - heal up well guys. Makes you grateful just to get round in one piece.
  6. The event facebook page says they will have Racetec there on the morning to process registrations...
