With my very limited knowledge of cycling I'd say you are going at a decent pace, even though your route is short enough.

If you're reasonably fit and you are pretty bollocksed when you arrive that is a non-scientific way of determining that you are going at a decent speed.

Why not change the knobblies for semi-slick MTB tyres? You'll be amazed at the difference.

In that case, 21km/h sounds very good. Switching the noise converters for slicks is the easiest way of making a big gain.

To work out watts per kg you need a powermeter or something that simulates one like TrainerRoad.com. Then you do a painful test called a CP20. If you want to do one without buying any kit you should be able to find a coach or uni sports science lab with a Watt Bike or Computrainer near you that will let you do one for a few quid. Test itself takes about an hour with warm up and cool down. The key (and hurty) part is a 20 minute interval where you try to hold the highest constant power you can sustain for 20 mins. It is difficult to get the pacing right on the first few goes, you tend to save yourself a bit too much and spike at the end or bury yourself early on and blow. The result of that test will give you your critical power for 20 (CP20) and 60 mins (CP60, which is 95% of CP20). CP60 is also known as your FTP or functional threshold power. Then you divide by your weight in kg.

Sounds intensive. I thought I'd be able to calculate it using some equations given that I knew my average speed and weight, but it doesn't seem to be possible.

You can have a play with this:

http://bikecalculator.com/

but there are so many variables that the results will be very approximate. e.g. if one person has a very low handlebar they may be more aero on the flats than someone else with a very upright position on the hoods or drops.

Did my new route to work in 30mins.

Very hot yesterday so got some sun 8)

With Slicks, and out of the wind, probably sub 25 mins.

Anyone got good brands for slick tyres?

I use them on my commute bike. GP4000S are faster but not quite as puncture resistant. Good resistance and durability for race tyres though, a lot of people use them for racing and training year round.

For MTB slicks, nimbus armadillos are good. Remember you don't need any tread at all since bike tyres van't aqua plane.

Getting caught in the wrong gear is a bitch isn't it?

Change down as early as possible but use the gears to try and maintain the same pedal cadence the entire way up the hill.

Make sure the seat is at the right height for hills as well otherwise your quads will really suffer on hillier rides. Leg should be nearly straight at the bottom of the stroke with your foot flat and your hips shouldn't wobble as you pedal.

Good job, keep at it and big improvements will come, you need to ride at least three times a week to get meaningful gains. Just remember that cycling is about learning to suffer, to quote the legendary Jens Voigt "..it doesn't get any easier, you just get faster..."

Maybe that's if the peloton is dictating the pace you ride at, but I've found after getting back on the bike the last 4-5 months that it gets both. I'm cruising up climbs now that were murdering me back in March/April, and set a PB on Strava yesterday up one that nearly had me walking when I first tried it.

JTB - to give you a reference point.

I'm 50 years old, 6'1" and 175lbs, I got into cycling three years ago and got serious about it this year. I train 3 times/week, generally structured intervals, etc. and ride with a club on weekends. My current FTP is 275 watts using the CTS 2 x 10 minute test. I ride a Specialized Tarmac carbon road bike and my typical average moving speed for a 60 mile weekend ride, on a reasonably flat circular route with typically a 10mph wind is: 20mph solo and 22.5mph in a group.

The point he's making is that if you bury yourself on every training session/ride you get faster (up to a point), so the suffering is constant. Since I have started taking my training seriously, it's now all FTP based. Every 6 weeks you reassess your FTP (hopefully up) and the target power for your intervals, etc. goes up correspondingly. So your RPE (rate of perceive exertion) stays the same.

However, if you’re riding the same route at the same speed, then yes it will get easier.

The bike was properly fitted so it should be fine, it is just getting used to being back in the saddle and correctly using the gears again. I think the problem was that I was changing down too much when the hill (barely) started to bite. Suddenly found I was putting in a lot of effort for very little gain and tired pretty quick.

Going out rowing tonight just to reassure myself that I am not an unfit lump!!

To a point, and then you'll stop improving.

Three times a week on the turbo trainer started today. I'm trying to get some legs so I don't get stuck somewhere too f**ked to get home, and I'm also trying to control the heartrate very strictly for the first few months. Read some interesting stuff the other week about cardiac output training, and the adaptations to various forms of exercise. Convinced me that for the sake of my heart, cycling was the way to go, with a few nice easy months of sessions around 45mins - 1hr at approx 140bpm. That's where I'm at cardio-wise, looking for improvements in left ventricle volume and muscle wall thickness.

The progression works in the way spyglass is talking about, over time it will require more work to get and keep the heartrate at that level. The 'distance' (turbo trainer though) travelled in 1hr will increase.

Longer term, the aim is to have a crack at the Cat and Fiddle in 2013, so will need to get on the road in the spring.

Does your app not calculate your "moving time"? Strava does for me; the 1:36 ride I did the other day came out the same total on Strava and on my Cateye, which is set to auto.

That one's a shocker - hard to believe he managed to walk away unscathed. His zen-like state of flow and connection to the bike didn't do him much good there.

The most important rule when riding a bike on the roads: be prepared (in all senses of the word) to slow down.

Had a ride last week up the Gospel pass just outside Hay On Wye, which at 8k is the longest climb in southern Britain. Given that our steepest local climb is the road bridge over the M69 I wasn't especially well prepared for this leg breaker, and it didn't help that my lowest sprocket was a 23 ( the deep section aero wheels were a big help :lol: ). It was, for me, brutal. The endless, short steep ramps made it very difficult to establish any kind of rhythm, and some sections were really nasty. There was no chance to work into it gradually, either, as the road rose up sharply within a couple of minutes of the start, so my decision to dispense with a warm up was particularly ill advised.

Based on a great deal of experience I thought I knew what my max HR was, but on one of the grimmest sections it rose to a disturbing 4 beats higher than I had previously seen and I began to wonder if I would survive. Mercifully, it flattened out a bit towards the top to provide some respite but even so, for most of the ascent my HR average was unpleasantly high and for long sections was within a few horrible % of max. It's a fantastic winding climb through marvelous country and when it opens out there are fabulous views all around. The road is single track but in good condition so the descent, though rarely straight, can be tackled at a good lick. There was very little traffic to worry about, but there were plenty of sheep around who always looked suspiciously like they were going to wander gormlessly into my path, but who nevertheless didn't spoil the exhilarating descent.

So it looks as though I'm surplus requirements for the school's rugby tour to the Caribbean next year, which isn't so bad as I hate the beach. I was thinking it might be a good time to visit the UK.

Questions:

1. Is it insane to think about cycling from Conwy to Cardiff in the middle of March? (Bear in mind I'm Canadian and an experienced cyclist who had no problems riding in -15 degree weather through the winter. That said, I'd rather not freeze to death or be constantly rained upon as the aforementioned riding was the daily 20 min trip to and from work, not 80kms through the rural highlands. I also do not mind hopping on a train to avoid the particularly nasty bits or if the weather is absolute shite.)

2. How likely would I be to obtain a ticket for the Wales v England encounter at Millennium?

Had about 10 rides on the new bike, furthest about 25 miles over some pretty hill terrain. What has surprised me is how devastating the wind is and how f**king terrible some of the roads are. Really enjoying it though.

A quick question, I have bought some fairly cheap shorts from Decathlon and although I am not having too much trouble, just how much benefit is there in the padding of the ones that are £50 plus.

I only ask because of the abovementioned blog - it's a ludicrously widely-used stock photo (in fact series of photos of the same bloke) that crops up everywhere in bike-related ads, posters etc, despite the guy not exactly fulfilling the approved look for the majority of the road cyclists these ads are usually aimed at. The guy that writes the blog calls him the 'time traveling t-shirt-wearing retro-Fred from the planet Tridork'
