Cervelo P3 Test Ride

I've posted a few times on my modifications to my set up of the Cervelo P3 (most recently on my home brew eTap wiring). The recent mods over the last few months include:

Indoor Training Part 5 - Rouvy in Workout Mode

Since the beginning of 2024 I've been increasingly using the Rouvy app in my indoor bike training (see Indoor Training - Part 3 Rouvy vs Zwift and Fulgaz). Until the other day I'd only been using this to enliven my indoor cycling on otherwise very dull interval sessions, but I thought I ought to give Rouvy's workouts a bit of a try. And I'm rather impressed.

The 2024 Time Trial Season

The start of my time trial season is looming ominously on the horizon. In 2024 I plan to ride more open events. Over the last couple of years I've ridden fewer open events (which are usually at weekends) because of various family issues. Mostly those issues have kept me from being able to race at weekends. Our club events are usually mid-week, and therefore have fit better with my lifestyle over the last couple of years.

VTTA Zwift '10' - Round 5 6/2/24

This was the fifth event in the VTTA's Zwift virtual 10 mile time trial series. Over the first four events, I'd seen a gradual improvement from 24:18 to 23:53. As far as I can tell, the improvement is mostly down to improved consistency in maintaining appropriate power levels, and this event saw my most consistent power so far.

My strategy for this was as follows.

VTTA 10 mile Winter TT league - Event 4 30/1/24

Another Tuesday, another VTTA Zwift time trial.

Aead of this time trial, I decided to splurge some of the 40+ million drops I'd accumulated in Zwift and buy the best frame and wheel combination available. At least as suggested by Zwift Insider. Armed with a (virtually) shiny new (virtual) cadex TT frame with (virtual) DT Swiss wheels, I entered the fourth in the eight event VTTA series.

Comparing power values - Tacx Neo vs Assioma pedals

Recently I'd become interested to see how the power reported by my ageing Tacx Neo smart trainer (first generation) compares with my Assioma pedals (i have the dual set). My initial investigations involved fitting the Assiomas to the bike mounted on the turbo and comparing the reported power by eye. This seemed to have a significant different at least at some power levers, so I felt some further investigations were merited.

VTTA 10 mile Winter TT league - Event 3 23/1/24

In this, my third event in the VTTA 10 mile Zwift TT series, I tried to maintain a steady power. I also tried ride this as I normally do road TTs - that is, at a very low cadence. This worked marginally - I seem to have improved by a piffling 4 seconds! At this rate I may have cracked 24 minutes by the end of the 8 events!

Indoor Training Part4 - Intervals.icu

I came across intervals.icu a couple of years ago, via an article written about 2021 Olympic road race winner Anna Keisenhofer. In the article she noted the complex and adaptable graphics that intervals.icu delivers, based on data drawn in from a number of sources.

VTTA 10 mile Winter TT league - Event 2 16/1/24

If I was a little disappointed at the outcome of my first effort at Zwift time trial racing last week, I did at least pace myself a bit better than I did in event #2. This was held on the same course as event #1, the pan-flat Tempus Fugit course. After a short delay occasioned by an unexpected Zwift update on the Apple TV, I set out to spin through a warm-up ride.

I’ve had a fairly heavy training load over the last week, so maybe I was left a bit jaded. However, the principal failing this evening was a that I didn’t keep a consistent power level through the event. Starting too hard was just the start. I lacked any kind of serious motivation, and repeatedly felt like I just wanted to stop. In fact there’s a surprising number of pauses in the record of the ride (see below).

My First Zwift Race


I've been using Zwift regularly since April 2020, when I was building back from being an 'early adopter' of Covid-19. In all that time, I've not raced in Zwift, and I've only very occasionally ridden with friends on Zwift.

Until now.

Indoor Training - Part 3 Rouvy vs Zwift and Fulgaz

Part 3 of this series is somewhat delayed by Christmas and associated shenanigans such as the traditional Christmas Cold, which really flattened me for a couple of weeks.

Indoor Training Part 2 - TrainerRoad

In Part 1 I described the hardware I use for cycle training indoors. In Part 2 I’ll describe the principal software package I use for indoor training, TrainerRoad. Part 3 will cover the other software I use, and Part4 the software I use for monitoring my progress (with some hardware comments).

There's a wide variety of apps out there for use with smart trainers. For some of these I'll only give a brief description in Part 3, while others I'll keep my comments very brief as I haven't used them extensively enough to form a valuable opinion.

Indoor Training Part 1 - Hardware

This is the first in a short series of posts in which I discuss my approach to training for cycle time trials. I find road cycling to be unsuitable for structured training sessions other than extended endurance sessions, due to a combination of climbs and descents (albeit pretty small around here), junctions, traffic lights and of course motor traffic. The exception to that would be the evening 10 mile time trials the club offers through the season, which provided an opportunity for riding at a high sustained pace for 20+ minutes.

In part 1, I’ll give a bit of background to the kit I use.

New aerobar set up for the Cervelo P3C - Part 1

In which I do yet another bout of TT bike fettling, this time to address the front end clutter.

Astwood '10' 26/8/23

In which I suffer a series of bike crises before even leaving the house, and have a lacklustre performance.

So as usual I started getting set up about an hour before I needed to set out for Astwood. When I came to pump the tyre up on the P5 TT bike, I found that the front wouldn't get up to my desired pressure, then the rear disk wouldn't stay inflated (I think because the valve core came a little loose). So I switched to the P3.

Cycling Through The Pandemic

Part 1 - 2020

So it will come as no surprise that 2020 was the weirdest cycling year since I came back to the sport in 1990.

Part 2 - Racing restarts 2021

2021 looked like it’d go the same way as 2020, with massive levels of infection, illness and death following the foolish decision by our pathetic and incompetent Government to grandstand over "not cancelling Christmas".  However, things did settle a bit, and by mid-April we felt able to start running our 2021 series of club time trials.

2019 Duo Normand

As I think I noted in one of the rare posts here this year, plans to ride the Duo Normand in 2019 were initially thwarted by a date clash, but ultimately the organisers rescheduled the event to 15th September (not, I think, in response to our inability to attend!) which meant that all systems were go. The main report is built using Microsoft Sway - you can either read it via this link: 2019 Duo Normand, or via the embedded version below. The four-way arrow icon will expand the Sway.

Time trials so far in 2019

So far this year, my racing has been characterised by lack-lustre performances, where I actually managed to complete a race. On the bright side, the recent change of date for the Duo Normand time trial in September now means that Team Grumpy can once again turn out. This gives a really good late season target for us!

The 2018 Duo Normand

We approached the 2018 Duo Normand with considerable interest, as there would be a new course used. Grumpy Bob had visited the course on a low intensity tandem trundle round at the end of August. But riding it on the TT bikes would offer a better idea of how the course might play out.

As per usual, as soon as weather forecasts became available on XC weather, we started looking ahead to 23rd September to get some kind of idea of what the conditions would be on the day, bearing in mid the lack of accuracy of longer term weather forecasts.

It was with mounting horror that we saw the predictions for strong winds. By the 17th September, we were looking at 28mph wind with 48mph gusts.
