Drive Time

Post by Joebasscat » September 4th, 2020, 1:22 pm

Thoughts on appropriate/adequate/reasonable drive time. Was watching a video where .70 sec was thrown out as common so decided I would check this morning a little closer. Assumed I would be slower. Surprisingly that was not the case, and during my warm up the .70 was common. When I checked at average 2K split it was in the .63 range while maintaining the same SPM as race pace. DF at 113.

My question stems from wanting to maintain the drive time for 2K pace throughout my workouts regardless of appropriate split for the workout. UT1, AT, TR etc... I imagine this requires adjusting the DF to the workout so a similar drive time can be maintained. I claim no knowledge, so just interested in others thoughts.

I have never thought about drive time, so I'm no help. I never even knew there was a common result.
46 HWT; 6' 4"; 1k= 3:09; 2k= 6:36; 5k= 17:24; 6k= 21:09; 10k= 35:46 30mins= 8,428m 60mins= 16,331m HM= 1:18:25; FM= 2:45:49; 50k= 3:21:14; 100k= 7:52:44; 12hrs = 153km

Didn’t mean to imply there was a “common” result since so many factors would play into it. Maybe “average”might be a better description.

Imo, I think it's a bit of superfluous data that could distract you from the important stuff.

Drive length is something that some of us get quite focused on, but in reality, due to physiology and rowing style this is different for different people but they could all have the same end result / pace.

If you concentrate on pace, average pace, watts, stroke rate and end results you will get all of the necessary information. Having said that, this might be important to you so hopefully others might be able to help.

I don't think I have ever swapped the display to drive time although by coincidence I was concentrating on my drive to recovery ratio last night as felt I was rushing my recovery on a slow r18/r19 hour piece.
An often quoted ratio is 2:1 for recovery to drive. ie. If rowing at 20spm then you are spending 3 secs per stroke, which at 2:1 would be 1sec drive and 2sec recovery. This is most often used for novices as a way to get them to stop rushing the recovery and something I was doing last night as realised my form had deserted me along with my posture and was lazily going up and down without driving properly. I didn't have ergdata connected though and was just counting in my head.
As spm goes up though your drive time to recovery ratio will get less.
On the water it's different as you are levering the boat past the oars, your 'puddle' being the pivot.. your drive speed is dictated by the speed of the boat. On the erg you are in control of your drive time.
Rambling slightly now! but as Dangerscouse says it's not something I would use in training either. As per last night I looked at my drive ratio as felt this wasn't right for the workout I was doing, I.e.being lazy with my form. So drive time in terms of ratio could be useful but think better measures to use, one being watching the power curve. There is a great video on this by one of the founders of Concept2.

Drive time is result of speed, drag, and strokelenght. Just looking at drive time alone makes not much sense.
Tbh never looked at it myself.
The most common way of thinking is looking at power per stroke. And use that, so look at your 2k strokepower and lower the rating to adjust for intensity. Stroketime will get longer at lower ratings that way.
