I make no secret of using e-assist, it's been a hard road back from my 2020 heart attack and, since starting this nth attempt to rebuild my endurance at brevet speed, I've been going for distance first. Strength will come with distance over time. With that in mind, every ride since January has been at 100% "euro boost", 250w, tapered and tailored by the electronics to need and economy. On Saturday just gone, I achieved my first 50km at better than 20km/h, but that ride, and every ride before it has been at 100% boost. Remember, riding, at this stage for endurance and brevet speed. Today, I went out at 80% boost - 200w Euro-style, 4 bars, not 5 - on a route that was a little more elevation over distance (200m over 32km compared to 170 over 50km) and was barely 1km/hour slower average speed. WITH TWENTY PERCENT LESS BOOST!!! So, from here, the next few weeks will be about rebuilding back to 50km in a sitting, but at 80% e-assist, then repeat at 60% and, so on. Once I can get to 40% boost, I'll start looking to cautiously extending out to 100km in a day in 2 sittings, either side of a lunch stop. All of this as Melbourne moves into its chilly, wet winter. I have the smell of the roads in my nostrils again! Now, if I can only get the knackered bottom bracket out of my 90s "acoustic" restomod build... --- Calories according to Cyclemeter: 902 Estimated e-assist Calories: 312 My effort: 590 Calories (kCal or 2468kj) (Estimates calculated from Watt hours using Energy Converter for iPhone) Route recorded in Cyclemeter for iPhone and all data is taken from that app because RWGPS truncates the route by obfuscating home/start location for security.
